* SPARK-1209 [CORE] (Take 2) SparkHadoop{MapRed,MapReduce}Util should not use ↵Sean Owen2014-11-095-5/+22
| | | | | | | | | | | | | | | | | | | | package org.apache.hadoop andrewor14 Another try at SPARK-1209, to address https://github.com/apache/spark/pull/2814#issuecomment-61197619 I successfully tested with `mvn -Dhadoop.version=1.0.4 -DskipTests clean package; mvn -Dhadoop.version=1.0.4 test` I assume that is what failed Jenkins last time. I also tried `-Dhadoop.version1.2.1` and `-Phadoop-2.4 -Pyarn -Phive` for more coverage. So this is why the class was put in `org.apache.hadoop` to begin with, I assume. One option is to leave this as-is for now and move it only when Hadoop 1.0.x support goes away. This is the other option, which adds a call to force the constructor to be public at run-time. It's probably less surprising than putting Spark code in `org.apache.hadoop`, but, does involve reflection. A `SecurityManager` might forbid this, but it would forbid a lot of stuff Spark does. This would also only affect Hadoop 1.0.x it seems.

* [SPARK-4225][SQL] Resorts to SparkContext.version to inspect Spark versionCheng Lian2014-11-071-17/+7
| | | | | | | | | | | | This PR resorts to `SparkContext.version` rather than META-INF/MANIFEST.MF in the assembly jar to inspect Spark version. Currently, when built with Maven, the MANIFEST.MF file in the assembly jar is incorrectly replaced by Guava 15.0 MANIFEST.MF, probably because of the assembly/shading tricks. Another related PR is #3103, which tries to fix the MANIFEST issue.

* [SPARK-4187] [Core] Switch to binary protocol for external shuffle service ↵Aaron Davidson2014-11-075-27/+29
| | | | | | | | | | | | | | | | | | messages This PR elimiantes the network package's usage of the Java serializer and replaces it with Encodable, which is a lightweight binary protocol. Each message is preceded by a type id, which will allow us to change messages (by only adding new ones), or to change the format entirely by switching to a special id (such as -1). This protocol has the advantage over Java that we can guarantee that messages will remain compatible across compiled versions and JVMs, though it does not provide a clean way to do schema migration. In the future, it may be good to use a more heavy-weight serialization format like protobuf, thrift, or avro, but these all add several dependencies which are unnecessary at the present time. Additionally this unifies the RPC messages of NettyBlockTransferService and ExternalShuffleClient.

* [SPARK-611] Display executor thread dumps in web UIJosh Rosen2014-11-0313-7/+247
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch allows executor thread dumps to be collected on-demand and viewed in the Spark web UI. The thread dumps are collected using Thread.getAllStackTraces(). To allow remote thread dumps to be triggered from the web UI, I added a new `ExecutorActor` that runs inside of the Executor actor system and responds to RPCs from the driver. The driver's mechanism for obtaining a reference to this actor is a little bit hacky: it uses the block manager master actor to determine the host/port of the executor actor systems in order to construct ActorRefs to ExecutorActor. Unfortunately, I couldn't find a much cleaner way to do this without a big refactoring of the executor -> driver communication.

* [SPARK-3791][SQL] Provides Spark version and Hive version in HiveThriftServer2Cheng Lian2014-11-021-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This PR overrides the `GetInfo` Hive Thrift API to provide correct version information. Another property `spark.sql.hive.version` is added to reveal the underlying Hive version. These are generally useful for Spark SQL ODBC driver providers. The Spark version information is extracted from the jar manifest. Also took the chance to remove the `SET -v` hack, which was a workaround for Simba ODBC driver connectivity. TODO - [x] Find a general way to figure out Hive (or even any dependency) version. This [blog post](http://blog.soebes.de/blog/2014/01/02/version-information-into-your-appas-with-maven/) suggests several methods to inspect application version. In the case of Spark, this can be tricky because the chosen method: 1. must applies to both Maven build and SBT build For Maven builds, we can retrieve the version information from the META-INF/maven directory within the assembly jar. But this doesn't work for SBT builds. 2. must not rely on the original jars of dependencies to extract specific dependency version, because Spark uses assembly jar. This implies we can't read Hive version from Hive jar files since standard Spark distribution doesn't include them. 3. should play well with `SPARK_PREPEND_CLASSES` to ease local testing during development. `SPARK_PREPEND_CLASSES` prevents classes to be loaded from the assembly jar, thus we can't locate the jar file and read its manifest. Given these, maybe the only reliable method is to generate a source file containing version information at build time. pwendell Do you have any suggestions from the perspective of the build process? **Update** Hive version is now retrieved from the newly introduced `HiveShim` object.

* [SPARK-3796] Create external service which can serve shuffle filesAaron Davidson2014-11-0123-222/+212
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces the tooling necessary to construct an external shuffle service which is independent of Spark executors, and then use this service inside Spark. An example (just for the sake of this PR) of the service creation can be found in Worker, and the service itself is used by plugging in the StandaloneShuffleClient as Spark's ShuffleClient (setup in BlockManager). This PR continues the work from #2753, which extracted out the transport layer of Spark's block transfer into an independent package within Spark. A new package was created which contains the Spark business logic necessary to retrieve the actual shuffle data, which is completely independent of the transport layer introduced in the previous patch. Similar to the transport layer, this package must not depend on Spark as we anticipate plugging this service as a lightweight process within, say, the YARN NodeManager, and do not wish to include Spark's dependencies (including Scala itself). There are several outstanding tasks which must be complete before this PR can be merged: - [x] Complete unit testing of network/shuffle package. - [x] Performance and correctness testing on a real cluster. - [x] Remove example service instantiation from Worker.scala. There are even more shortcomings of this PR which should be addressed in followup patches: - Don't use Java serializer for RPC layer! It is not cross-version compatible. - Handle shuffle file cleanup for dead executors once the application terminates or the ContextCleaner triggers. - Documentation of the feature in the Spark docs. - Improve behavior if the shuffle service itself goes down (right now we don't blacklist it, and new executors cannot spawn on that machine). - SSL and SASL integration - Nice to have: Handle shuffle file consolidation (this would requires changes to Spark's implementation).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The additions add the abstract BinaryFileInputFormat and BinaryRecordReader classes for reading in data as a byte stream and converting it to another format using the ```def parseByteArray(inArray: Array[Byte]): T``` function. As a trivial example ```ByteInputFormat``` and ```ByteRecordReader``` are included which just return the Array[Byte] from a given file. Finally a RDD for ```BinaryFileInputFormat``` (to allow for easier partitioning changes as was done for WholeFileInput) was added and the appropriate byteFiles to the ```SparkContext``` so the functions can be easily used by others.

All of these metrics are now hidden by default. This allows advanced users to look at more detailed metrics, without distracting the average user. This change also cleans up the stage detail page so that metrics are shown in the same order in the summary table as in the task table, and updates the metrics in both tables such that they contain the same set of metrics. The ability to remember a user's preferences for which metrics should be shown has been filed as SPARK-4024.

All changes in functionality are made in `SparkSubmit.scala` (~20 lines). **SPARK-3319.** There is currently a divergence in behavior when the user passes in additional jars through `--jars` and through setting `spark.jars` in the default properties file. The former will happily resolve the paths (e.g. convert `my.jar` to `file:/absolute/path/to/my.jar`), while the latter does not. We should resolve paths consistently in both cases. This also applies to the following pairs of command line arguments and Spark configs: - `--jars` ~ `spark.jars` - `--files` ~ `spark.files` / `spark.yarn.dist.files` - `--archives` ~ `spark.yarn.dist.archives` - `--py-files` ~ `spark.submit.pyFiles` **SPARK-3338.** This PR also fixes the following bug: if the user sets `spark.submit.pyFiles` in his/her properties file, it does not actually get picked up even if `--py-files` is not set.

* [SPARK-3822] Executor scaling mechanism for YarnAndrew Or2014-10-296-41/+302
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is part of a broader effort to enable dynamic scaling of executors ([SPARK-3174](https://issues.apache.org/jira/browse/SPARK-3174)). This is intended to work alongside SPARK-3795 (#2746), SPARK-3796 and SPARK-3797, but is functionally independently of these other issues. The logic is built on top of PraveenSeluka's changes at #2798. This is different from the changes there in a few major ways: (1) the mechanism is implemented within the existing scheduler backend framework rather than in new `Actor` classes. This also introduces a parent abstract class `YarnSchedulerBackend` to encapsulate common logic to communicate with the Yarn `ApplicationMaster`. (2) The interface of requesting executors exposed to the `SparkContext` is the same, but the communication between the scheduler backend and the AM uses total number executors desired instead of an incremental number. This is discussed in #2746 and explained in the comments in the code. I have tested this significantly on a stable Yarn cluster. ------------ A remaining task for this issue is to tone down the error messages emitted when an executor is removed. Currently, `SparkContext` and its components react as if the executor has failed, resulting in many scary error messages and eventual timeouts. While it's not strictly necessary to fix this as of the first-cut implementation of this mechanism, it would be good to add logic to distinguish this case. I prefer to address this in a separate PR. I have filed a separate JIRA for this task at SPARK-4134.
