* [YARN][DOC] Increasing NodeManager's heap size with External Shuffle ServiceArtur Sukhenko2016-11-161-0/+2
| | | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? Suggest users to increase `NodeManager's` heap size if `External Shuffle Service` is enabled as `NM` can spend a lot of time doing GC resulting in shuffle operations being a bottleneck due to `Shuffle Read blocked time` bumped up. Also because of GC `NodeManager` can use an enormous amount of CPU and cluster performance will suffer. I have seen NodeManager using 5-13G RAM and up to 2700% CPU with `spark_shuffle` service on. ## How was this patch tested? #### Added step 5: ![shuffle_service](https://cloud.githubusercontent.com/assets/15244468/20355499/2fec0fde-ac2a-11e6-8f8b-1c80daf71be1.png) Author: Artur Sukhenko <artur.sukhenko@gmail.com> Closes #15906 from Devian-ua/nmHeapSize.
* [SPARK-1267][SPARK-18129] Allow PySpark to be pip installedHolden Karau2016-11-162-1/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? This PR aims to provide a pip installable PySpark package. This does a bunch of work to copy the jars over and package them with the Python code (to prevent challenges from trying to use different versions of the Python code with different versions of the JAR). It does not currently publish to PyPI but that is the natural follow up (SPARK-18129). Done: - pip installable on conda [manual tested] - setup.py installed on a non-pip managed system (RHEL) with YARN [manual tested] - Automated testing of this (virtualenv) - packaging and signing with release-build* Possible follow up work: - release-build update to publish to PyPI (SPARK-18128) - figure out who owns the pyspark package name on prod PyPI (is it someone with in the project or should we ask PyPI or should we choose a different name to publish with like ApachePySpark?) - Windows support and or testing ( SPARK-18136 ) - investigate details of wheel caching and see if we can avoid cleaning the wheel cache during our test - consider how we want to number our dev/snapshot versions Explicitly out of scope: - Using pip installed PySpark to start a standalone cluster - Using pip installed PySpark for non-Python Spark programs *I've done some work to test release-build locally but as a non-committer I've just done local testing. ## How was this patch tested? Automated testing with virtualenv, manual testing with conda, a system wide install, and YARN integration. release-build changes tested locally as a non-committer (no testing of upload artifacts to Apache staging websites) Author: Holden Karau <holden@us.ibm.com> Author: Juliet Hougland <juliet@cloudera.com> Author: Juliet Hougland <not@myemail.com> Closes #15659 from holdenk/SPARK-1267-pip-install-pyspark.

* [SPARK-16759][CORE] Add a configuration property to pass caller contexts of ↵Weiqing Yang2016-11-111-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | upstream applications into Spark ## What changes were proposed in this pull request? Many applications take Spark as a computing engine and run on it. This PR adds a configuration property `spark.log.callerContext` that can be used by Spark's upstream applications (e.g. Oozie) to set up their caller contexts into Spark. In the end, Spark will combine its own caller context with the caller contexts of its upstream applications, and write them into Yarn RM log and HDFS audit log. The audit log has a config to truncate the caller contexts passed in (default 128). The caller contexts will be sent over rpc, so it should be concise. The call context written into HDFS log and Yarn log consists of two parts: the information `A` specified by Spark itself and the value `B` of `spark.log.callerContext` property. Currently `A` typically takes 64 to 74 characters, so `B` can have up to 50 characters (mentioned in the doc `running-on-yarn.md`) ## How was this patch tested? Manual tests. I have run some Spark applications with `spark.log.callerContext` configuration in Yarn client/cluster mode, and verified that the caller contexts were written into Yarn RM log and HDFS audit log correctly. The ways to configure `spark.log.callerContext` property: - In spark-defaults.conf: ``` spark.log.callerContext infoSpecifiedByUpstreamApp ``` - In app's source code: ``` val spark = SparkSession .builder .appName("SparkKMeans") .config("spark.log.callerContext", "infoSpecifiedByUpstreamApp") .getOrCreate() ``` When running on Spark Yarn cluster mode, the driver is unable to pass 'spark.log.callerContext' to Yarn client and AM since Yarn client and AM have already started before the driver performs `.config("spark.log.callerContext", "infoSpecifiedByUpstreamApp")`. The following example shows the command line used to submit a SparkKMeans application and the corresponding records in Yarn RM log and HDFS audit log. Command: ``` ./bin/spark-submit --verbose --executor-cores 3 --num-executors 1 --master yarn --deploy-mode client --class org.apache.spark.examples.SparkKMeans examples/target/original-spark-examples_2.11-2.1.0-SNAPSHOT.jar hdfs://localhost:9000/lr_big.txt 2 5 ``` Yarn RM log: <img width="1440" alt="screen shot 2016-10-19 at 9 12 03 pm" src="https://cloud.githubusercontent.com/assets/8546874/19547050/7d2f278c-9649-11e6-9df8-8d5ff12609f0.png"> HDFS audit log: <img width="1400" alt="screen shot 2016-10-19 at 10 18 14 pm" src="https://cloud.githubusercontent.com/assets/8546874/19547102/096060ae-964a-11e6-981a-cb28efd5a058.png"> Author: Weiqing Yang <yangweiqing001@gmail.com> Closes #15563 from weiqingy/SPARK-16759.
* [SPARK-13331] AES support for over-the-wire encryptionJunjie Chen2016-11-111-0/+26
| | | | | | | | | | | | | | | ## What changes were proposed in this pull request? DIGEST-MD5 mechanism is used for SASL authentication and secure communication. DIGEST-MD5 mechanism supports 3DES, DES, and RC4 ciphers. However, 3DES, DES and RC4 are slow relatively. AES provide better performance and security by design and is a replacement for 3DES according to NIST. Apache Common Crypto is a cryptographic library optimized with AES-NI, this patch employ Apache Common Crypto as enc/dec backend for SASL authentication and secure channel to improve spark RPC. ## How was this patch tested? Unit tests and Integration test. Author: Junjie Chen <junjie.j.chen@intel.com> Closes #15172 from cjjnjust/shuffle_rpc_encrypt.

* [SPARK-17350][SQL] Disable default use of KryoSerializer in Thrift ServerJosh Rosen2016-11-011-3/+2
| | | | | | | | | | | | | | In SPARK-4761 / #3621 (December 2014) we enabled Kryo serialization by default in the Spark Thrift Server. However, I don't think that the original rationale for doing this still holds now that most Spark SQL serialization is now performed via encoders and our UnsafeRow format. In addition, the use of Kryo as the default serializer can introduce performance problems because the creation of new KryoSerializer instances is expensive and we haven't performed instance-reuse optimizations in several code paths (including DirectTaskResult deserialization). Given all of this, I propose to revert back to using JavaSerializer as the default serializer in the Thrift Server. /cc liancheng Author: Josh Rosen <joshrosen@databricks.com> Closes #14906 from JoshRosen/disable-kryo-in-thriftserver.

* [SPARK-17637][SCHEDULER] Packed scheduling for Spark tasks across executorsZhan Zhang2016-10-151-0/+11
| | | | | | | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? Restructure the code and implement two new task assigner. PackedAssigner: try to allocate tasks to the executors with least available cores, so that spark can release reserved executors when dynamic allocation is enabled. BalancedAssigner: try to allocate tasks to the executors with more available cores in order to balance the workload across all executors. By default, the original round robin assigner is used. We test a pipeline, and new PackedAssigner save around 45% regarding the reserved cpu and memory with dynamic allocation enabled. ## How was this patch tested? (Please explain how this patch was tested. E.g. unit tests, integration tests, manual tests) Both unit test in TaskSchedulerImplSuite and manual tests in production pipeline. Author: Zhan Zhang <zhanzhang@fb.com> Closes #15218 from zhzhan/packed-scheduler.

* [SPARK-17675][CORE] Expand Blacklist for TaskSetsImran Rashid2016-10-121-0/+43
| | | | | | | | | | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? This is a step along the way to SPARK-8425. To enable incremental review, the first step proposed here is to expand the blacklisting within tasksets. In particular, this will enable blacklisting for * (task, executor) pairs (this already exists via an undocumented config) * (task, node) * (taskset, executor) * (taskset, node) Adding (task, node) is critical to making spark fault-tolerant of one-bad disk in a cluster, without requiring careful tuning of "spark.task.maxFailures". The other additions are also important to avoid many misleading task failures and long scheduling delays when there is one bad node on a large cluster. Note that some of the code changes here aren't really required for just this -- they put pieces in place for SPARK-8425 even though they are not used yet (eg. the `BlacklistTracker` helper is a little out of place, `TaskSetBlacklist` holds onto a little more info than it needs to for just this change, and `ExecutorFailuresInTaskSet` is more complex than it needs to be). ## How was this patch tested? Added unit tests, run tests via jenkins. Author: Imran Rashid <irashid@cloudera.com> Author: mwws <wei.mao@intel.com> Closes #15249 from squito/taskset_blacklist_only.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | in JDBC datasource package ## What changes were proposed in this pull request? This PR proposes to fix arbitrary usages among `Map[String, String]`, `Properties` and `JDBCOptions` instances for options in `execution/jdbc` package and make the connection properties exclude Spark-only options. This PR includes some changes as below: - Unify `Map[String, String]`, `Properties` and `JDBCOptions` in `execution/jdbc` package to `JDBCOptions`. - Move `batchsize`, `fetchszie`, `driver` and `isolationlevel` options into `JDBCOptions` instance. - Document `batchSize` and `isolationlevel` with marking both read-only options and write-only options. Also, this includes minor types and detailed explanation for some statements such as url. - Throw exceptions fast by checking arguments first rather than in execution time (e.g. for `fetchsize`). - Exclude Spark-only options in connection properties. ## How was this patch tested? Existing tests should cover this. Author: hyukjinkwon <gurwls223@gmail.com> Closes #15292 from HyukjinKwon/SPARK-17719.
