* [SPARK-15199][SQL] Disallow Dropping Build-in Functionsgatorsmile2016-05-092-1/+26
| | | | | | | | | | | | #### What changes were proposed in this pull request? As Hive and the major RDBMS behave, the built-in functions are not allowed to drop. In the current implementation, users can drop the built-in functions. However, after dropping the built-in functions, users are unable to add them back. #### How was this patch tested? Added a test case. Author: gatorsmile <gatorsmile@gmail.com> Closes #12975 from gatorsmile/dropBuildInFunction.

* [MINOR] [SPARKR] Update data-manipulation.R to use native csv readerYanbo Liang2016-05-094-12/+8
| | | | | | | | | | | | | ## What changes were proposed in this pull request? * Since Spark has supported native csv reader, it does not necessary to use the third party ```spark-csv``` in ```examples/src/main/r/data-manipulation.R```. Meanwhile, remove all ```spark-csv``` usage in SparkR. * Running R applications through ```sparkR``` is not supported as of Spark 2.0, so we change to use ```./bin/spark-submit``` to run the example. ## How was this patch tested? Offline test. Author: Yanbo Liang <ybliang8@gmail.com> Closes #13005 from yanboliang/r-df-examples.
* [SPARK-14459][SQL] Detect relation partitioning and adjust the logical planRyan Blue2016-05-095-12/+143
| | | | | | | | | | | | | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? This detects a relation's partitioning and adds checks to the analyzer. If an InsertIntoTable node has no partitioning, it is replaced by the relation's partition scheme and input columns are correctly adjusted, placing the partition columns at the end in partition order. If an InsertIntoTable node has partitioning, it is checked against the table's reported partitions. These changes required adding a PartitionedRelation trait to the catalog interface because Hive's MetastoreRelation doesn't extend CatalogRelation. This commit also includes a fix to InsertIntoTable's resolved logic, which now detects that all expected columns are present, including dynamic partition columns. Previously, the number of expected columns was not checked and resolved was true if there were missing columns. ## How was this patch tested? This adds new tests to the InsertIntoTableSuite that are fixed by this PR. Author: Ryan Blue <blue@apache.org> Closes #12239 from rdblue/SPARK-14459-detect-hive-partitioning.

* [SPARK-15184][SQL] Fix Silent Removal of An Existent Temp Table by Rename Tablegatorsmile2016-05-092-0/+69
| | | | | | | | | | | | | | #### What changes were proposed in this pull request? Currently, if we rename a temp table `Tab1` to another existent temp table `Tab2`. `Tab2` will be silently removed. This PR is to detect it and issue an exception message. In addition, this PR also detects another issue in the rename table command. When the destination table identifier does have database name, we should not ignore them. That might mean users could rename a regular table. #### How was this patch tested? Added two related test cases Author: gatorsmile <gatorsmile@gmail.com> Closes #12959 from gatorsmile/rewriteTable.

| | | | | | | | | | | | | | | | Table/Function/Partitions by Rename #### What changes were proposed in this pull request? So far, in the implementation of InMemoryCatalog, we do not check if the new/destination table/function/partition exists or not. Thus, we just silently remove the existent table/function/partition. This PR is to detect them and issue an appropriate exception. #### How was this patch tested? Added the related test cases. They also verify if HiveExternalCatalog also detects these errors.

* [SPARK-15122] [SQL] Fix TPC-DS 41 - Normalize predicates before pulling them outHerman van Hovell2016-05-062-1/+15
| | | | | | | | | | | | | | ## What changes were proposed in this pull request? The official TPC-DS 41 query currently fails because it contains a scalar subquery with a disjunctive correlated predicate (the correlated predicates were nested in ORs). This makes the `Analyzer` pull out the entire predicate which is wrong and causes the following (correct) analysis exception: `The correlated scalar subquery can only contain equality predicates` This PR fixes this by first simplifing (or normalizing) the correlated predicates before pulling them out of the subquery. ## How was this patch tested? Manual testing on TPC-DS 41, and added a test to SubquerySuite. Author: Herman van Hovell <hvanhovell@questtec.nl> Closes #12954 from hvanhovell/SPARK-15122.
* [SPARK-15051][SQL] Create a TypedColumn aliasKevin Yu2016-05-072-6/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? Currently when we create an alias against a TypedColumn from user-defined Aggregator(for example: agg(aggSum.toColumn as "a")), spark is using the alias' function from Column( as), the alias function will return a column contains a TypedAggregateExpression, which is unresolved because the inputDeserializer is not defined. Later the aggregator function (agg) will inject the inputDeserializer back to the TypedAggregateExpression, but only if the aggregate columns are TypedColumn, in the above case, the TypedAggregateExpression will remain unresolved because it is under column and caused the problem reported by this jira [15051](https://issues.apache.org/jira/browse/SPARK-15051?jql=project%20%3D%20SPARK). This PR propose to create an alias function for TypedColumn, it will return a TypedColumn. It is using the similar code path as Column's alia function. For the spark build in aggregate function, like max, it is working with alias, for example val df1 = Seq(1 -> "a", 2 -> "b", 3 -> "b").toDF("i", "j") checkAnswer(df1.agg(max("j") as "b"), Row(3) :: Nil) Thanks for comments. ## How was this patch tested?

* [SPARK-1239] Improve fetching of map output statusesThomas Graves2016-05-067-84/+290
| | | | | | | | | | | | | | | | | | | | | | | | | | | The main issue we are trying to solve is the memory bloat of the Driver when tasks request the map output statuses. This means with a large number of tasks you either need a huge amount of memory on Driver or you have to repartition to smaller number. This makes it really difficult to run over say 50000 tasks. The main issues that cause the memory bloat are: 1) no flow control on sending the map output status responses. We serialize the map status output and then hand off to netty to send. netty is sending asynchronously and it can't send them fast enough to keep up with incoming requests so we end up with lots of copies of the serialized map output statuses sitting there and this causes huge bloat when you have 10's of thousands of tasks and map output status is in the 10's of MB. 2) When initial reduce tasks are started up, they all request the map output statuses from the Driver. These requests are handled by multiple threads in parallel so even though we check to see if we have a cached version, initially when we don't have a cached version yet, many of initial requests can all end up serializing the exact same map output statuses. This patch does a couple of things: - When the map output status size is over a threshold (default 512K) then it uses broadcast to send the map statuses. This means we no longer serialize a large map output status and thus we don't have issues with memory bloat. the messages sizes are now in the 300-400 byte range and the map status output are broadcast. If its under the threadshold it sends it as before, the message contains the DIRECT indicator now. - synchronize the incoming requests to allow one thread to cache the serialized output and broadcast the map output status that can then be used by everyone else. This ensures we don't create multiple broadcast variables when we don't need to. To ensure this happens I added a second thread pool which the Dispatcher hands the requests to so that those threads can block without blocking the main dispatcher threads (which would cause things like heartbeats and such not to come through) Note that some of design and code was contributed by mridulm ## How was this patch tested? Unit tests and a lot of manually testing. Ran with akka and netty rpc. Ran with both dynamic allocation on and off. one of the large jobs I used to test this was a join of 15TB of data. it had 200,000 map tasks, and 20,000 reduce tasks. Executors ranged from 200 to 2000. This job ran successfully with 5GB of memory on the driver with these changes. Without these changes I was using 20GB and only had 500 reduce tasks. The job has 50mb of serialized map output statuses and took roughly the same amount of time for the executors to get the map output statuses as before. Ran a variety of other jobs, from large wordcounts to small ones not using broadcasts. Author: Thomas Graves <tgraves@staydecay.corp.gq1.yahoo.com> Closes #12113 from tgravescs/SPARK-1239.

* [SPARK-14962][SQL] Do not push down isnotnull/isnull on unsuportted types in ORChyukjinkwon2016-05-076-56/+126
| | | | | | | | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? https://issues.apache.org/jira/browse/SPARK-14962 ORC filters were being pushed down for all types for both `IsNull` and `IsNotNull`. This is apparently OK because both `IsNull` and `IsNotNull` do not take a type as an argument (Hive 1.2.x) during building filters (`SearchArgument`) in Spark-side but they do not filter correctly because stored statistics always produces `null` for not supported types (eg `ArrayType`) in ORC-side. So, it is always `true` for `IsNull` which ends up with always `false` for `IsNotNull`. (Please see [RecordReaderImpl.java#L296-L318](https://github.com/apache/hive/blob/branch-1.2/ql/src/java/org/apache/hadoop/hive/ql/io/orc/RecordReaderImpl.java#L296-L318) and [RecordReaderImpl.java#L359-L365](https://github.com/apache/hive/blob/branch-1.2/ql/src/java/org/apache/hadoop/hive/ql/io/orc/RecordReaderImpl.java#L359-L365) in Hive 1.2) This looks prevented in Hive 1.3.x >= by forcing to give a type ([`PredicateLeaf.Type`](https://github.com/apache/hive/blob/e085b7e9bd059d91aaf013df0db4d71dca90ec6f/storage-api/src/java/org/apache/hadoop/hive/ql/io/sarg/PredicateLeaf.java#L50-L56)) when building a filter ([`SearchArgument`](https://github.com/apache/hive/blob/26b5c7b56a4f28ce3eabc0207566cce46b29b558/storage-api/src/java/org/apache/hadoop/hive/ql/io/sarg/SearchArgument.java#L260)) but Hive 1.2.x seems not doing this. This PR prevents ORC filter creation for `IsNull` and `IsNotNull` on unsupported types. `OrcFilters` resembles `ParquetFilters`. ## How was this patch tested? Unittests in `OrcQuerySuite` and `OrcFilterSuite` and `sbt scalastyle`.

| | | | | | | | | | | This patch has the new logic from #8512 that uses a parallel collection to compute partitions in UnionRDD. The rest of #8512 added an alternative code path for calculating splits in S3, but that isn't necessary to get the same speedup. The underlying problem wasn't that bulk listing wasn't used, it was that an extra FileStatus was retrieved for each file. The fix was just committed as [HADOOP-12810](https://issues.apache.org/jira/browse/HADOOP-12810). (I think the original commit also used a single prefix to enumerate all paths, but that isn't always helpful and it was removed in later versions so there is no need for SparkS3Utils.) I tested this using the same table that piapiaozhexiu was using. Calculating splits for a 10-day period took 25 seconds with this change and HADOOP-12810, which is on par with the results from #8512.

* [SPARK-14139][SQL] RowEncoder should preserve schema nullabilityWenchen Fan2016-05-064-16/+88
| | | | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? The problem is: In `RowEncoder`, we use `Invoke` to get the field of an external row, which lose the nullability information. This PR creates a `GetExternalRowField` expression, so that we can preserve the nullability info. TODO: simplify the null handling logic in `RowEncoder`, to remove so many if branches, in follow-up PR. ## How was this patch tested? new tests in `RowEncoderSuite` Note that, This PR takes over https://github.com/apache/spark/pull/11980, with a little simplification, so all credits should go to koertkuipers Author: Wenchen Fan <wenchen@databricks.com> Author: Koert Kuipers <koert@tresata.com> Closes #12364 from cloud-fan/nullable.
* [SPARK-14915][CORE] Don't re-queue a task if another attempt has already ↵Jason Moore2016-05-051-1/+10
| | | | | | | | | | | | | | | | succeeded ## What changes were proposed in this pull request? Don't re-queue a task if another attempt has already succeeded. This currently happens when a speculative task is denied from committing the result due to another copy of the task already having succeeded. ## How was this patch tested? I'm running a job which has a fair bit of skew in the processing time across the tasks for speculation to trigger in the last quarter (default settings), causing many commit denied exceptions to be thrown. Previously, these tasks were then being retried over and over again until the stage possibly completes (despite using compute resources on these superfluous tasks). With this change (applied to the 1.6 branch), they no longer retry and the stage completes successfully without these extra task attempts.

| | | | | | | | | | | | | | | | "BETA" ## What changes were proposed in this pull request? Copy the package documentation from Scala/Java to Python for ML package and remove beta tags. Not super sure if we want to keep the BETA tag but since we are making it the default it seems like probably the time to remove it (happy to put it back in if we want to keep it BETA). ## How was this patch tested? Python documentation built locally as HTML and text and verified output. Author: Holden Karau <holden@us.ibm.com> Closes #12883 from holdenk/SPARK-15106-add-pyspark-package-doc-for-ml.
* [SPARK-12154] Upgrade to Jersey 2mcheah2016-05-0514-131/+244
| | | | | | | | | | | | | | ## What changes were proposed in this pull request? Replace com.sun.jersey with org.glassfish.jersey. Changes to the Spark Web UI code were required to compile. The changes were relatively standard Jersey migration things. ## How was this patch tested? I did a manual test for the standalone web APIs. Although I didn't test the functionality of the security filter itself, the code that changed non-trivially is how we actually register the filter. I attached a debugger to the Spark master and verified that the SecurityFilter code is indeed invoked upon hitting /api/v1/applications. Author: mcheah <mcheah@palantir.com> Closes #12715 from mccheah/feature/upgrade-jersey.

Make sure that whenever the StateStoreCoordinator cannot be contacted, assume that the SparkContext and RpcEnv on the driver has been shutdown, and therefore stop the StateStore management thread, and unload all loaded stores. ## How was this patch tested? Updated unit tests. Author: Tathagata Das <tathagata.das1565@gmail.com> Closes #12905 from tdas/SPARK-15131.
* [SPARK-14993][SQL] Fix Partition Discovery Inconsistency when Input is a ↵gatorsmile2016-05-042-14/+88
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Path to Parquet File #### What changes were proposed in this pull request? When we load a dataset, if we set the path to ```/path/a=1```, we will not take `a` as the partitioning column. However, if we set the path to ```/path/a=1/file.parquet```, we take `a` as the partitioning column and it shows up in the schema. This PR is to fix the behavior inconsistency issue. The base path contains a set of paths that are considered as the base dirs of the input datasets. The partitioning discovery logic will make sure it will stop when it reaches any base path. By default, the paths of the dataset provided by users will be base paths. Below are three typical cases, **Case 1**```sqlContext.read.parquet("/path/something=true/")```: the base path will be `/path/something=true/`, and the returned DataFrame will not contain a column of `something`. **Case 2**```sqlContext.read.parquet("/path/something=true/a.parquet")```: the base path will be still `/path/something=true/`, and the returned DataFrame will also not contain a column of `something`. **Case 3**```sqlContext.read.parquet("/path/")```: the base path will be `/path/`, and the returned DataFrame will have the column of `something`. Users also can override the basePath by setting `basePath` in the options to pass the new base path to the data source. For example, ```sqlContext.read.option("basePath", "/path/").parquet("/path/something=true/")```, and the returned DataFrame will have the column of `something`.
