* [SPARK-20343][BUILD] Avoid Unidoc build only if Hadoop 2.6 is explicitly set ↵hyukjinkwon2017-04-191-12/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | in SBT build ## What changes were proposed in this pull request? This PR proposes two things as below: - Avoid Unidoc build only if Hadoop 2.6 is explicitly set in SBT build Due to a different dependency resolution in SBT & Unidoc by an unknown reason, the documentation build fails on a specific machine & environment in Jenkins but it was unable to reproduce. So, this PR just checks an environment variable `AMPLAB_JENKINS_BUILD_PROFILE` that is set in Hadoop 2.6 SBT build against branches on Jenkins, and then disables Unidoc build. **Note that PR builder will still build it with Hadoop 2.6 & SBT.** ``` ======================================================================== Building Unidoc API Documentation ======================================================================== [info] Building Spark unidoc (w/Hive 1.2.1) using SBT with these arguments: -Phadoop-2.6 -Pmesos -Pkinesis-asl -Pyarn -Phive-thriftserver -Phive unidoc Using /usr/java/jdk1.8.0_60 as default JAVA_HOME. ... ``` I checked the environment variables from the logs (first bit) as below: - **spark-master-test-sbt-hadoop-2.6** (this one is being failed) - https://amplab.cs.berkeley.edu/jenkins/view/Spark%20QA%20Test%20(Dashboard)/job/spark-master-test-sbt-hadoop-2.6/lastBuild/consoleFull ``` JAVA_HOME=/usr/java/jdk1.8.0_60 JAVA_7_HOME=/usr/java/jdk1.7.0_79 SPARK_BRANCH=master AMPLAB_JENKINS_BUILD_PROFILE=hadoop2.6 <- I use this variable AMPLAB_JENKINS="true" ``` - spark-master-test-sbt-hadoop-2.7 - https://amplab.cs.berkeley.edu/jenkins/view/Spark%20QA%20Test%20(Dashboard)/job/spark-master-test-sbt-hadoop-2.7/lastBuild/consoleFull ``` JAVA_HOME=/usr/java/jdk1.8.0_60 JAVA_7_HOME=/usr/java/jdk1.7.0_79 SPARK_BRANCH=master AMPLAB_JENKINS_BUILD_PROFILE=hadoop2.7 AMPLAB_JENKINS="true" ``` - spark-master-test-maven-hadoop-2.6 - https://amplab.cs.berkeley.edu/jenkins/view/Spark%20QA%20Test%20(Dashboard)/job/spark-master-test-maven-hadoop-2.6/lastBuild/consoleFull ``` JAVA_HOME=/usr/java/jdk1.8.0_60 JAVA_7_HOME=/usr/java/jdk1.7.0_79 HADOOP_PROFILE=hadoop-2.6 HADOOP_VERSION= SPARK_BRANCH=master AMPLAB_JENKINS="true" ``` - spark-master-test-maven-hadoop-2.7 - https://amplab.cs.berkeley.edu/jenkins/view/Spark%20QA%20Test%20(Dashboard)/job/spark-master-test-maven-hadoop-2.7/lastBuild/consoleFull ``` JAVA_HOME=/usr/java/jdk1.8.0_60 JAVA_7_HOME=/usr/java/jdk1.7.0_79 HADOOP_PROFILE=hadoop-2.7 HADOOP_VERSION= SPARK_BRANCH=master AMPLAB_JENKINS="true" ``` - PR builder - https://amplab.cs.berkeley.edu/jenkins/job/SparkPullRequestBuilder/75843/consoleFull ``` JENKINS_MASTER_HOSTNAME=amp-jenkins-master JAVA_HOME=/usr/java/jdk1.8.0_60 JAVA_7_HOME=/usr/java/jdk1.7.0_79 ``` Assuming from other logs in branch-2.1 - SBT & Hadoop 2.6 against branch-2.1 https://amplab.cs.berkeley.edu/jenkins/view/Spark%20QA%20Test%20(Dashboard)/job/spark-branch-2.1-test-sbt-hadoop-2.6/lastBuild/consoleFull ``` JAVA_HOME=/usr/java/jdk1.8.0_60 JAVA_7_HOME=/usr/java/jdk1.7.0_79 SPARK_BRANCH=branch-2.1 AMPLAB_JENKINS_BUILD_PROFILE=hadoop2.6 AMPLAB_JENKINS="true" ``` - Maven & Hadoop 2.6 against branch-2.1 https://amplab.cs.berkeley.edu/jenkins/view/Spark%20QA%20Test%20(Dashboard)/job/spark-branch-2.1-test-maven-hadoop-2.6/lastBuild/consoleFull ``` JAVA_HOME=/usr/java/jdk1.8.0_60 JAVA_7_HOME=/usr/java/jdk1.7.0_79 HADOOP_PROFILE=hadoop-2.6 HADOOP_VERSION= SPARK_BRANCH=branch-2.1 AMPLAB_JENKINS="true" ``` We have been using the same convention for those variables.

I am unable to reproduce this - https://github.com/apache/spark/pull/17477#issuecomment-294094092 and the reviewer was too. So, this got merged as it looks the only way to verify this is to merge it currently (as no one seems able to reproduce this). ## How was this patch tested? I only checked `is_hadoop_version_2_6 = os.environ.get("AMPLAB_JENKINS_BUILD_PROFILE") == "hadoop2.6"` is working fine as expected as below: ```python >>> import collections >>> os = collections.namedtuple('os', 'environ')(environ={"AMPLAB_JENKINS_BUILD_PROFILE": "hadoop2.6"}) >>> print(not os.environ.get("AMPLAB_JENKINS_BUILD_PROFILE") == "hadoop2.6") False >>> os = collections.namedtuple('os', 'environ')(environ={"AMPLAB_JENKINS_BUILD_PROFILE": "hadoop2.7"}) >>> print(not os.environ.get("AMPLAB_JENKINS_BUILD_PROFILE") == "hadoop2.6") True >>> os = collections.namedtuple('os', 'environ')(environ={}) >>> print(not os.environ.get("AMPLAB_JENKINS_BUILD_PROFILE") == "hadoop2.6") True ``` I tried many ways but I was unable to reproduce this in my local.

* [SPARK-17019][CORE] Expose on-heap and off-heap memory usage in various placesjerryshao2017-04-061-1/+10
| | | | | | | | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? With [SPARK-13992](https://issues.apache.org/jira/browse/SPARK-13992), Spark supports persisting data into off-heap memory, but the usage of on-heap and off-heap memory is not exposed currently, it is not so convenient for user to monitor and profile, so here propose to expose off-heap memory as well as on-heap memory usage in various places: 1. Spark UI's executor page will display both on-heap and off-heap memory usage. 2. REST request returns both on-heap and off-heap memory. 3. Also this can be gotten from MetricsSystem. 4. Last this usage can be obtained programmatically from SparkListener. Attach the UI changes: ![screen shot 2016-08-12 at 11 20 44 am](https://cloud.githubusercontent.com/assets/850797/17612032/6c2f4480-607f-11e6-82e8-a27fb8cbb4ae.png) Backward compatibility is also considered for event-log and REST API. Old event log can still be replayed with off-heap usage displayed as 0. For REST API, only adds the new fields, so JSON backward compatibility can still be kept. ## How was this patch tested? Unit test added and manual verification. Author: jerryshao <sshao@hortonworks.com> Closes #14617 from jerryshao/SPARK-17019.
* [SPARK-17471][ML] Add compressed method to ML matricessethah2017-03-241-1/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? This patch adds a `compressed` method to ML `Matrix` class, which returns the minimal storage representation of the matrix - either sparse or dense. Because the space occupied by a sparse matrix is dependent upon its layout (i.e. column major or row major), this method must consider both cases. It may also be useful to force the layout to be column or row major beforehand, so an overload is added which takes in a `columnMajor: Boolean` parameter. The compressed implementation relies upon two new abstract methods `toDense(columnMajor: Boolean)` and `toSparse(columnMajor: Boolean)`, similar to the compressed method implemented in the `Vector` class. These methods also allow the layout of the resulting matrix to be specified via the `columnMajor` parameter. More detail on the new methods is given below. ## How was this patch tested? Added many new unit tests ## New methods (summary, not exhaustive list) **Matrix trait** - `private[ml] def toDenseMatrix(columnMajor: Boolean): DenseMatrix` (abstract) - converts the matrix (either sparse or dense) to dense format - `private[ml] def toSparseMatrix(columnMajor: Boolean): SparseMatrix` (abstract) - converts the matrix (either sparse or dense) to sparse format - `def toDense: DenseMatrix = toDense(true)` - converts the matrix (either sparse or dense) to dense format in column major layout - `def toSparse: SparseMatrix = toSparse(true)` - converts the matrix (either sparse or dense) to sparse format in column major layout - `def compressed: Matrix` - finds the minimum space representation of this matrix, considering both column and row major layouts, and converts it - `def compressed(columnMajor: Boolean): Matrix` - finds the minimum space representation of this matrix considering only column OR row major, and converts it **DenseMatrix class** - `private[ml] def toDenseMatrix(columnMajor: Boolean): DenseMatrix` - converts the dense matrix to a dense matrix, optionally changing the layout (data is NOT duplicated if the layouts are the same) - `private[ml] def toSparseMatrix(columnMajor: Boolean): SparseMatrix` - converts the dense matrix to sparse matrix, using the specified layout **SparseMatrix class** - `private[ml] def toDenseMatrix(columnMajor: Boolean): DenseMatrix` - converts the sparse matrix to a dense matrix, using the specified layout - `private[ml] def toSparseMatrix(columnMajors: Boolean): SparseMatrix` - converts the sparse matrix to sparse matrix. If the sparse matrix contains any explicit zeros, they are removed. If the layout requested does not match the current layout, data is copied to a new representation. If the layouts match and no explicit zeros exist, the current matrix is returned. Author: sethah <seth.hendrickson16@gmail.com> Closes #15628 from sethah/matrix_compress.
* [SPARK-19820][CORE] Add interface to kill tasks w/ a reasonEric Liang2017-03-231-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | This commit adds a killTaskAttempt method to SparkContext, to allow users to kill tasks so that they can be re-scheduled elsewhere. This also refactors the task kill path to allow specifying a reason for the task kill. The reason is propagated opaquely through events, and will show up in the UI automatically as `(N killed: $reason)` and `TaskKilled: $reason`. Without this change, there is no way to provide the user feedback through the UI. Currently used reasons are "stage cancelled", "another attempt succeeded", and "killed via SparkContext.killTask". The user can also specify a custom reason through `SparkContext.killTask`. cc rxin In the stage overview UI the reasons are summarized: ![1](https://cloud.githubusercontent.com/assets/14922/23929209/a83b2862-08e1-11e7-8b3e-ae1967bbe2e5.png) Within the stage UI you can see individual task kill reasons: ![2](https://cloud.githubusercontent.com/assets/14922/23929200/9a798692-08e1-11e7-8697-72b27ad8a287.png) Existing tests, tried killing some stages in the UI and verified the messages are as expected.

* [SPARK-19876][SS][WIP] OneTime Trigger ExecutorTyson Condie2017-03-231-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? An additional trigger and trigger executor that will execute a single trigger only. One can use this OneTime trigger to have more control over the scheduling of triggers. In addition, this patch requires an optimization to StreamExecution that logs a commit record at the end of successfully processing a batch. This new commit log will be used to determine the next batch (offsets) to process after a restart, instead of using the offset log itself to determine what batch to process next after restart; using the offset log to determine this would process the previously logged batch, always, thus not permitting a OneTime trigger feature. ## How was this patch tested? A number of existing tests have been revised. These tests all assumed that when restarting a stream, the last batch in the offset log is to be re-processed. Given that we now have a commit log that will tell us if that last batch was processed successfully, the results/assumptions of those tests needed to be revised accordingly. In addition, a OneTime trigger test was added to StreamingQuerySuite, which tests: - The semantics of OneTime trigger (i.e., on start, execute a single batch, then stop). - The case when the commit log was not able to successfully log the completion of a batch before restart, which would mean that we should fall back to what's in the offset log. - A OneTime trigger execution that results in an exception being thrown. marmbrus tdas zsxwing Please review http://spark.apache.org/contributing.html before opening a pull request.

* [SPARK-17498][ML] StringIndexer enhancement for handling unseen labelsVinceShieh2017-03-071-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? This PR is an enhancement to ML StringIndexer. Before this PR, String Indexer only supports "skip"/"error" options to deal with unseen records. But those unseen records might still be useful and user would like to keep the unseen labels in certain use cases, This PR enables StringIndexer to support keeping unseen labels as indices [numLabels].

* [SPARK-19276][CORE] Fetch Failure handling robust to user error handlingImran Rashid2017-03-021-0/+3
| | | | | | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? Fault-tolerance in spark requires special handling of shuffle fetch failures. The Executor would catch FetchFailedException and send a special msg back to the driver. However, intervening user code could intercept that exception, and wrap it with something else. This even happens in SparkSQL. So rather than checking the thrown exception only, we'll store the fetch failure directly in the TaskContext, where users can't touch it. ## How was this patch tested? Added a test case which failed before the fix. Full test suite via jenkins. Author: Imran Rashid <irashid@cloudera.com> Closes #16639 from squito/SPARK-19276.
* [SPARK-19652][UI] Do auth checks for REST API access.Marcelo Vanzin2017-02-211-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The REST API has a security filter that performs auth checks based on the UI root's security manager. That works fine when the UI root is the app's UI, but not when it's the history server. In the SHS case, all users would be allowed to see all applications through the REST API, even if the UI itself wouldn't be available to them. This change adds auth checks for each app access through the API too, so that only authorized users can see the app's data. The change also modifies the existing security filter to use `HttpServletRequest.getRemoteUser()`, which is used in other places. That is not necessarily the same as the principal's name; for example, when using Hadoop's SPNEGO auth filter, the remote user strips the realm information, which then matches the user name registered as the owner of the application. I also renamed the UIRootFromServletContext trait to a more generic name since I'm using it to store more context information now. Tested manually with an authentication filter enabled.

Adding convenience function to Python `JavaWrapper` so that it is easy to create a Py4J JavaArray that is compatible with current class constructors that have a Scala `Array` as input so that it is not necessary to have a Java/Python friendly constructor. The function takes a Java class as input that is used by Py4J to create the Java array of the given class. As an example, `OneVsRest` has been updated to use this and the alternate constructor is removed. ## How was this patch tested?

| | | | | | | | | | | | | | | | | | | | ### What changes were proposed in this pull request? Currently, we only have a SQL interface for recovering all the partitions in the directory of a table and update the catalog. `MSCK REPAIR TABLE` or `ALTER TABLE table RECOVER PARTITIONS`. (Actually, very hard for me to remember `MSCK` and have no clue what it means) After the new "Scalable Partition Handling", the table repair becomes much more important for making visible the data in the created data source partitioned table. Thus, this PR is to add it into the Catalog interface. After this PR, users can repair the table by ```Scala spark.catalog.recoverPartitions("testTable") ``` ### How was this patch tested? Modified the existing test cases. Author: gatorsmile <gatorsmile@gmail.com> Closes #16356 from gatorsmile/repairTable.
* [SPARK-18842][TESTS][LAUNCHER] De-duplicate paths in classpaths in commands ↵hyukjinkwon2016-12-141-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | for local-cluster mode to work around the path length limitation on Windows ## What changes were proposed in this pull request? Currently, some tests are being failed and hanging on Windows due to this problem. For the reason in SPARK-18718, some tests using `local-cluster` mode were disabled on Windows due to the length limitation by paths given to classpaths. The limitation seems roughly 32K (see the [blog in MS](https://blogs.msdn.microsoft.com/oldnewthing/20031210-00/?p=41553/) and [another reference](https://support.thoughtworks.com/hc/en-us/articles/213248526-Getting-around-maximum-command-line-length-is-32767-characters-on-Windows)) but in `local-cluster` mode, executors were being launched as processes with the command such as [here](https://gist.github.com/HyukjinKwon/5bc81061c250d4af5a180869b59d42ea) in (only) tests. This length is roughly 40K due to the classpaths given to `java` command. However, it seems duplicates are almost half of them. So, if we deduplicate the paths, it seems reduced to roughly 20K with the command, [here](https://gist.github.com/HyukjinKwon/dad0c8db897e5e094684a2dc6a417790). Maybe, we should consider as some more paths are added in the future but it seems better than disabling all the tests for now with minimised changes. Therefore, this PR proposes to deduplicate the paths in classpaths in case of launching executors as processes in `local-cluster` mode. ## How was this patch tested?

* [SPARK-18657][SPARK-18668] Make StreamingQuery.id persists across restart ↵Tathagata Das2016-12-051-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | and not auto-generate StreamingQuery.name ## What changes were proposed in this pull request? Here are the major changes in this PR. - Added the ability to recover `StreamingQuery.id` from checkpoint location, by writing the id to `checkpointLoc/metadata`. - Added `StreamingQuery.runId` which is unique for every query started and does not persist across restarts. This is to identify each restart of a query separately (same as earlier behavior of `id`). - Removed auto-generation of `StreamingQuery.name`. The purpose of name was to have the ability to define an identifier across restarts, but since id is precisely that, there is no need for a auto-generated name. This means name becomes purely cosmetic, and is null by default. - Added `runId` to `StreamingQueryListener` events and `StreamingQueryProgress`. Implementation details - Renamed existing `StreamExecutionMetadata` to `OffsetSeqMetadata`, and moved it to the file `OffsetSeq.scala`, because that is what this metadata is tied to. Also did some refactoring to make the code cleaner (got rid of a lot of `.json` and `.getOrElse("{}")`). - Added the `id` as the new `StreamMetadata`. - When a StreamingQuery is created it gets or writes the `StreamMetadata` from `checkpointLoc/metadata`. - All internal logging in `StreamExecution` uses `(name, id, runId)` instead of just `name` TODO - [x] Test handling of name=null in json generation of StreamingQueryProgress - [x] Test handling of name=null in json generation of StreamingQueryListener events - [x] Test python API of runId ## How was this patch tested?

| | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? SPARK-18429 introduced count-min sketch aggregate function for SQL, but the implementation and testing is more complicated than needed. This simplifies the test cases and removes support for data types that don't have clear equality semantics: 1. Removed support for floating point and decimal types. 2. Removed the heavy randomized tests. The underlying CountMinSketch implementation already had pretty good test coverage through randomized tests, and the SPARK-18429 implementation is just to add an aggregate function wrapper around CountMinSketch. There is no need for randomized tests at three different levels of the implementations. ## How was this patch tested? A lot of the change is to simplify test cases. Author: Reynold Xin <rxin@databricks.com> Closes #16093 from rxin/SPARK-18663.

This PR only tries to fix things that looks pretty straightforward and were fixed in other previous PRs before. This PR roughly fixes several things as below: - Fix unrecognisable class and method links in javadoc by changing it from `[[..]]` to `` `...` `` ``` [error] .../spark/sql/core/target/java/org/apache/spark/sql/streaming/DataStreamReader.java:226: error: reference not found [error] * Loads text files and returns a {link DataFrame} whose schema starts with a string column named ``` - Fix an exception annotation and remove code backticks in `throws` annotation Currently, sbt unidoc with Java 8 complains as below: ``` [error] .../java/org/apache/spark/sql/streaming/StreamingQuery.java:72: error: unexpected text [error] * throws StreamingQueryException, if <code>this</code> query has terminated with an exception. ``` `throws` should specify the correct class name from `StreamingQueryException,` to `StreamingQueryException` without backticks. (see [JDK-8007644](https://bugs.openjdk.java.net/browse/JDK-8007644)). - Fix `[[http..]]` to `<a href="http..."></a>`. ```diff - * [[https://blogs.oracle.com/java-platform-group/entry/diagnosing_tls_ssl_and_https Oracle - * blog page]]. + * <a href="https://blogs.oracle.com/java-platform-group/entry/diagnosing_tls_ssl_and_https"> + * Oracle blog page</a>. ``` `[[http...]]` link markdown in scaladoc is unrecognisable in javadoc. - It seems class can't have `return` annotation.

* [SPARK-18236] Reduce duplicate objects in Spark UI and HistoryServerJosh Rosen2016-11-071-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? When profiling heap dumps from the HistoryServer and live Spark web UIs, I found a large amount of memory being wasted on duplicated objects and strings. This patch's changes remove most of this duplication, resulting in over 40% memory savings for some benchmarks. - **Task metrics** (6441f0624dfcda9c7193a64bfb416a145b5aabdf): previously, every `TaskUIData` object would have its own instances of `InputMetricsUIData`, `OutputMetricsUIData`, `ShuffleReadMetrics`, and `ShuffleWriteMetrics`, but for many tasks these metrics are irrelevant because they're all zero. This patch changes how we construct these metrics in order to re-use a single immutable "empty" value for the cases where these metrics are empty. - **TaskInfo.accumulables** (ade86db901127bf13c0e0bdc3f09c933a093bb76): Previously, every `TaskInfo` object had its own empty `ListBuffer` for holding updates from named accumulators. Tasks which didn't use named accumulators still paid for the cost of allocating and storing this empty buffer. To avoid this overhead, I changed the `val` with a mutable buffer into a `var` which holds an immutable Scala list, allowing tasks which do not have named accumulator updates to share the same singleton `Nil` object. - **String.intern() in JSONProtocol** (7e05630e9a78c455db8c8c499f0590c864624e05): in the HistoryServer, executor hostnames and ids are deserialized from JSON, leading to massive duplication of these string objects. By calling `String.intern()` on the deserialized values we can remove all of this duplication. Since Spark now requires Java 7+ we don't have to worry about string interning exhausting the permgen (see http://java-performance.info/string-intern-in-java-6-7-8/). ## How was this patch tested? I ran ``` sc.parallelize(1 to 100000, 100000).count() ``` in `spark-shell` with event logging enabled, then loaded that event log in the HistoryServer, performed a full GC, and took a heap dump. According to YourKit, the changes in this patch reduced memory consumption by roughly 28 megabytes (or 770k Java objects): ![image](https://cloud.githubusercontent.com/assets/50748/19953276/4f3a28aa-a129-11e6-93df-d7fa91396f66.png) Here's a table illustrating the drop in objects due to deduplication (the drop is <100k for some objects because some events were dropped from the listener bus; this is a separate, existing bug that I'll address separately after CPU-profiling): ![image](https://cloud.githubusercontent.com/assets/50748/19953290/6a271290-a129-11e6-93ad-b825f1448886.png) Author: Josh Rosen <joshrosen@databricks.com> Closes #15743 from JoshRosen/spark-ui-memory-usage.

Here is the design doc for implementing the necessary metrics. https://docs.google.com/document/d/1NIdcGuR1B3WIe8t7VxLrt58TJB4DtipWEbj5I_mzJys/edit?usp=sharing Specifically, this PR adds the following public APIs changes. ### New APIs - `StreamingQuery.status` returns a `StreamingQueryStatus` object (renamed from `StreamingQueryInfo`, see later) - `StreamingQueryStatus` has the following important fields - inputRate - Current rate (rows/sec) at which data is being generated by all the sources - processingRate - Current rate (rows/sec) at which the query is processing data from all the sources - ~~outputRate~~ - *Does not work with wholestage codegen* - latency - Current average latency between the data being available in source and the sink writing the corresponding output - sourceStatuses: Array[SourceStatus] - Current statuses of the sources - sinkStatus: SinkStatus - Current status of the sink - triggerStatus - Low-level detailed status of the last completed/currently active trigger - latencies - getOffset, getBatch, full trigger, wal writes - timestamps - trigger start, finish, after getOffset, after getBatch - numRows - input, output, state total/updated rows for aggregations - `SourceStatus` has the following important fields - inputRate - Current rate (rows/sec) at which data is being generated by the source - processingRate - Current rate (rows/sec) at which the query is processing data from the source - triggerStatus - Low-level detailed status of the last completed/currently active trigger - Python API for `StreamingQuery.status()` ### Breaking changes to existing APIs **Existing direct public facing APIs** - Deprecated direct public-facing APIs `StreamingQuery.sourceStatuses` and `StreamingQuery.sinkStatus` in favour of `StreamingQuery.status.sourceStatuses/sinkStatus`. - Branch 2.0 should have it deprecated, master should have it removed. **Existing advanced listener APIs** - `StreamingQueryInfo` renamed to `StreamingQueryStatus` for consistency with `SourceStatus`, `SinkStatus` - Earlier StreamingQueryInfo was used only in the advanced listener API, but now it is used in direct public-facing API (StreamingQuery.status) - Field `queryInfo` in listener events `QueryStarted`, `QueryProgress`, `QueryTerminated` changed have name `queryStatus` and return type `StreamingQueryStatus`. - Field `offsetDesc` in `SourceStatus` was Option[String], converted it to `String`. - For `SourceStatus` and `SinkStatus` made constructor private instead of private[sql] to make them more java-safe. Instead added `private[sql] object SourceStatus/SinkStatus.apply()` which are harder to accidentally use in Java. ## How was this patch tested? Old and new unit tests. - Rate calculation and other internal logic of StreamMetrics tested by StreamMetricsSuite. - New info in statuses returned through StreamingQueryListener is tested in StreamingQueryListenerSuite. - New and old info returned through StreamingQuery.status is tested in StreamingQuerySuite. - Source-specific tests for making sure input rows are counted are is source-specific test suites. - Additional tests to test minor additions in LocalTableScanExec, StateStore, etc. Metrics also manually tested using Ganglia sink Author: Tathagata Das <tathagata.das1565@gmail.com> Closes #15307 from tdas/SPARK-17731.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? Global temporary view is a cross-session temporary view, which means it's shared among all sessions. Its lifetime is the lifetime of the Spark application, i.e. it will be automatically dropped when the application terminates. It's tied to a system preserved database `global_temp`(configurable via SparkConf), and we must use the qualified name to refer a global temp view, e.g. SELECT * FROM global_temp.view1. changes for `SessionCatalog`: 1. add a new field `gloabalTempViews: GlobalTempViewManager`, to access the shared global temp views, and the global temp db name. 2. `createDatabase` will fail if users wanna create `global_temp`, which is system preserved. 3. `setCurrentDatabase` will fail if users wanna set `global_temp`, which is system preserved. 4. add `createGlobalTempView`, which is used in `CreateViewCommand` to create global temp views. 5. add `dropGlobalTempView`, which is used in `CatalogImpl` to drop global temp view. 6. add `alterTempViewDefinition`, which is used in `AlterViewAsCommand` to update the view definition for local/global temp views. 7. `renameTable`/`dropTable`/`isTemporaryTable`/`lookupRelation`/`getTempViewOrPermanentTableMetadata`/`refreshTable` will handle global temp views. changes for SQL commands: 1. `CreateViewCommand`/`AlterViewAsCommand` is updated to support global temp views 2. `ShowTablesCommand` outputs a new column `database`, which is used to distinguish global and local temp views. 3. other commands can also handle global temp views if they call `SessionCatalog` APIs which accepts global temp views, e.g. `DropTableCommand`, `AlterTableRenameCommand`, `ShowColumnsCommand`, etc. changes for other public API 1. add a new method `dropGlobalTempView` in `Catalog` 2. `Catalog.findTable` can find global temp view 3. add a new method `createGlobalTempView` in `Dataset` ## How was this patch tested? new tests in `SQLViewSuite` Author: Wenchen Fan <wenchen@databricks.com> Closes #14897 from cloud-fan/global-temp-view.
* [SPARK-17346][SQL] Add Kafka source for Structured StreamingShixiong Zhu2016-10-051-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? This PR adds a new project ` external/kafka-0-10-sql` for Structured Streaming Kafka source. It's based on the design doc: https://docs.google.com/document/d/19t2rWe51x7tq2e5AOfrsM9qb8_m7BRuv9fel9i0PqR8/edit?usp=sharing tdas did most of work and part of them was inspired by koeninger's work. ### Introduction The Kafka source is a structured streaming data source to poll data from Kafka. The schema of reading data is as follows: Column | Type ---- | ---- key | binary value | binary topic | string partition | int offset | long timestamp | long timestampType | int The source can deal with deleting topics. However, the user should make sure there is no Spark job processing the data when deleting a topic. ### Configuration The user can use `DataStreamReader.option` to set the following configurations. Kafka Source's options | value | default | meaning ------ | ------- | ------ | ----- startingOffset | ["earliest", "latest"] | "latest" | The start point when a query is started, either "earliest" which is from the earliest offset, or "latest" which is just from the latest offset. Note: This only applies when a new Streaming query is started, and that resuming will always pick up from where the query left off. failOnDataLost | [true, false] | true | Whether to fail the query when it's possible that data is lost (e.g., topics are deleted, or offsets are out of range). This may be a false alarm. You can disable it when it doesn't work as you expected. subscribe | A comma-separated list of topics | (none) | The topic list to subscribe. Only one of "subscribe" and "subscribeParttern" options can be specified for Kafka source. subscribePattern | Java regex string | (none) | The pattern used to subscribe the topic. Only one of "subscribe" and "subscribeParttern" options can be specified for Kafka source. kafka.consumer.poll.timeoutMs | long | 512 | The timeout in milliseconds to poll data from Kafka in executors fetchOffset.numRetries | int | 3 | Number of times to retry before giving up fatch Kafka latest offsets. fetchOffset.retryIntervalMs | long | 10 | milliseconds to wait before retrying to fetch Kafka offsets Kafka's own configurations can be set via `DataStreamReader.option` with `kafka.` prefix, e.g, `stream.option("kafka.bootstrap.servers", "host:port")` ### Usage * Subscribe to 1 topic ```Scala spark .readStream .format("kafka") .option("kafka.bootstrap.servers", "host:port") .option("subscribe", "topic1") .load() ``` * Subscribe to multiple topics ```Scala spark .readStream .format("kafka") .option("kafka.bootstrap.servers", "host:port") .option("subscribe", "topic1,topic2") .load() ``` * Subscribe to a pattern ```Scala spark .readStream .format("kafka") .option("kafka.bootstrap.servers", "host:port") .option("subscribePattern", "topic.*") .load() ``` ## How was this patch tested?

* [SPARK-17671][WEBUI] Spark 2.0 history server summary page is slow even set ↵Sean Owen2016-10-041-0/+2
| | | | | | | | | | | | | | | | | | spark.history.ui.maxApplications ## What changes were proposed in this pull request? Return Iterator of applications internally in history server, for consistency and performance. See https://github.com/apache/spark/pull/15248 for some back-story. The code called by and calling HistoryServer.getApplicationList wants an Iterator, but this method materializes an Iterable, which potentially causes a performance problem. It's simpler too to make this internal method also pass through an Iterator. ## How was this patch tested? Existing tests.

* [SPARK-17717][SQL] Add Exist/find methods to Catalog [FOLLOW-UP]Herman van Hovell2016-10-011-6/+4
| | | | | | | | | | | | ## What changes were proposed in this pull request? We added find and exists methods for Databases, Tables and Functions to the user facing Catalog in PR https://github.com/apache/spark/pull/15301. However, it was brought up that the semantics of the `find` methods are more in line a `get` method (get an object or else fail). So we rename these in this PR. ## How was this patch tested? Existing tests. Author: Herman van Hovell <hvanhovell@databricks.com> Closes #15308 from hvanhovell/SPARK-17717-2.
* [SPARK-17717][SQL] Add exist/find methods to Catalog.Herman van Hovell2016-09-291-1/+10
| | | | | | | | | | | | ## What changes were proposed in this pull request? The current user facing catalog does not implement methods for checking object existence or finding objects. You could theoretically do this using the `list*` commands, but this is rather cumbersome and can actually be costly when there are many objects. This PR adds `exists*` and `find*` methods for Databases, Table and Functions. ## How was this patch tested? Added tests to `org.apache.spark.sql.internal.CatalogSuite` Author: Herman van Hovell <hvanhovell@databricks.com> Closes #15301 from hvanhovell/SPARK-17717.

| | | | | | | | | | | | | | | ## What changes were proposed in this pull request? Several performance improvement for ```ChiSqSelector```: 1, Keep ```selectedFeatures``` ordered ascendent. ```ChiSqSelectorModel.transform``` need ```selectedFeatures``` ordered to make prediction. We should sort it when training model rather than making prediction, since users usually train model once and use the model to do prediction multiple times. 2, When training ```fpr``` type ```ChiSqSelectorModel```, it's not necessary to sort the ChiSq test result by statistic. ## How was this patch tested? Existing unit tests. Author: Yanbo Liang <ybliang8@gmail.com> Closes #15277 from yanboliang/spark-17704.
