* [SPARK-12080][CORE] Kryo - Support multiple user registratorsrotems2015-12-041-2/+2

* [SPARK-12081] Make unified memory manager work with small heapsAndrew Or2015-12-011-2/+2
| | | | | | | | | | The existing `spark.memory.fraction` (default 0.75) gives the system 25% of the space to work with. For small heaps, this is not enough: e.g. default 1GB leaves only 250MB system memory. This is especially a problem in local mode, where the driver and executor are crammed in the same JVM. Members of the community have reported driver OOM's in such cases. **New proposal.** We now reserve 300MB before taking the 75%. For 1GB JVMs, this leaves `(1024 - 300) * 0.75 = 543MB` for execution and storage. This is proposal (1) listed in the [JIRA](https://issues.apache.org/jira/browse/SPARK-12081). Author: Andrew Or <andrew@databricks.com> Closes #10081 from andrewor14/unified-memory-small-heaps.

* [SPARK-11140][CORE] Transfer files using network lib when using NettyRpcEnv.Marcelo Vanzin2015-11-231-0/+2
| | | | | | | | | | | | | | | | This change abstracts the code that serves jars / files to executors so that each RpcEnv can have its own implementation; the akka version uses the existing HTTP-based file serving mechanism, while the netty versions uses the new stream support added to the network lib, which makes file transfers benefit from the easier security configuration of the network library, and should also reduce overhead overall. The change includes a small fix to TransportChannelHandler so that it propagates user events to downstream handlers. Author: Marcelo Vanzin <vanzin@cloudera.com> Closes #9530 from vanzin/SPARK-11140.

* [SPARK-10971][SPARKR] RRunner should allow setting path to Rscript.Sun Rui2015-10-231-0/+18
| | | | | | | | | | | | | | | | | Add a new spark conf option "spark.sparkr.r.driver.command" to specify the executable for an R script in client modes. The existing spark conf option "spark.sparkr.r.command" is used to specify the executable for an R script in cluster modes for both driver and workers. See also [launch R worker script](https://github.com/apache/spark/blob/master/core/src/main/scala/org/apache/spark/api/r/RRDD.scala#L395). BTW, [envrionment variable "SPARKR_DRIVER_R"](https://github.com/apache/spark/blob/master/launcher/src/main/java/org/apache/spark/launcher/SparkSubmitCommandBuilder.java#L275) is used to locate R shell on the local host. For your information, PYSPARK has two environment variables serving simliar purpose: PYSPARK_PYTHON Python binary executable to use for PySpark in both driver and workers (default is `python`). PYSPARK_DRIVER_PYTHON Python binary executable to use for PySpark in driver only (default is PYSPARK_PYTHON). pySpark use the code [here](https://github.com/apache/spark/blob/master/core/src/main/scala/org/apache/spark/deploy/PythonRunner.scala#L41) to determine the python executable for a python script.

* [SPARK-10708] Consolidate sort shuffle implementationsJosh Rosen2015-10-221-5/+2
| | | | | | | | There's a lot of duplication between SortShuffleManager and UnsafeShuffleManager. Given that these now provide the same set of functionality, now that UnsafeShuffleManager supports large records, I think that we should replace SortShuffleManager's serialized shuffle implementation with UnsafeShuffleManager's and should merge the two managers together.

* [SPARK-10983] Unified memory managerAndrew Or2015-10-131-29/+70
| | | | | | | | | | | | | | | | This patch unifies the memory management of the storage and execution regions such that either side can borrow memory from each other. When memory pressure arises, storage will be evicted in favor of execution. To avoid regressions in cases where storage is crucial, we dynamically allocate a fraction of space for storage that execution cannot evict. Several configurations are introduced: - **spark.memory.fraction (default 0.75)**: ​fraction of the heap space used for execution and storage. The lower this is, the more frequently spills and cached data eviction occur. The purpose of this config is to set aside memory for internal metadata, user data structures, and imprecise size estimation in the case of sparse, unusually large records. - **spark.memory.storageFraction (default 0.5)**: size of the storage region within the space set aside by `s​park.memory.fraction`. ​Cached data may only be evicted if total storage exceeds this region. - **spark.memory.useLegacyMode (default false)**: whether to use the memory management that existed in Spark 1.5 and before. This is mainly for backward compatibility. For a detailed description of the design, see [SPARK-10000](https://issues.apache.org/jira/browse/SPARK-10000). This patch builds on top of the `MemoryManager` interface introduced in #9000. Author: Andrew Or <andrew@databricks.com> Closes #9084 from andrewor14/unified-memory-manager.

* [SPARK-10710] Remove ability to disable spilling in core and SQLJosh Rosen2015-09-191-11/+3
| | | | | | | | | | It does not make much sense to set `spark.shuffle.spill` or `spark.sql.planner.externalSort` to false: I believe that these configurations were initially added as "escape hatches" to guard against bugs in the external operators, but these operators are now mature and well-tested. In addition, these configurations are not handled in a consistent way anymore: SQL's Tungsten codepath ignores these configurations and will continue to use spilling operators. Similarly, Spark Core's `tungsten-sort` shuffle manager does not respect `spark.shuffle.spill=false`. This pull request removes these configurations, adds warnings at the appropriate places, and deletes a large amount of code which was only used in code paths that did not support spilling.

| | | | | | | | | | | | | | | | | | | | | | | | spark.localExecution.enabled Spark has an option called spark.localExecution.enabled; according to the docs: > Enables Spark to run certain jobs, such as first() or take() on the driver, without sending tasks to the cluster. This can make certain jobs execute very quickly, but may require shipping a whole partition of data to the driver. This feature ends up adding quite a bit of complexity to DAGScheduler, especially in the runLocallyWithinThread method, but as far as I know nobody uses this feature (I searched the mailing list and haven't seen any recent mentions of the configuration nor stacktraces including the runLocally method). As a step towards scheduler complexity reduction, I propose that we remove this feature and all code related to it for Spark 1.5. This pull request simply brings #7484 up to date.

* [SPARK-9244] Increase some memory defaultsMatei Zaharia2015-07-221-9/+7
| | | | | | | | | | | | | | | | | | | There are a few memory limits that people hit often and that we could make higher, especially now that memory sizes have grown. - spark.akka.frameSize: This defaults at 10 but is often hit for map output statuses in large shuffles. This memory is not fully allocated up-front, so we can just make this larger and still not affect jobs that never sent a status that large. We increase it to 128. - spark.executor.memory: Defaults at 512m, which is really small. We increase it to 1g.

* SPARK-1706: Allow multiple executors per worker in Standalone modeCodingCat2015-04-141-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | resubmit of https://github.com/apache/spark/pull/636 for a totally different algorithm https://issues.apache.org/jira/browse/SPARK-1706 In current implementation, the user has to start multiple workers in a server for starting multiple executors in a server, which introduces additional overhead due to the more JVM processes... In this patch, I changed the scheduling logic in master to enable the user to start multiple executor processes within the same JVM process. 1. user configure spark.executor.maxCoreNumPerExecutor to suggest the maximum core he/she would like to allocate to each executor 2. Master assigns the executors to the workers with the major consideration on the memoryPerExecutor and the worker.freeMemory, and tries to allocate as many as possible cores to the executor ```min(min(memoryPerExecutor, worker.freeCore), maxLeftCoreToAssign)``` where ```maxLeftCoreToAssign = maxExecutorCanAssign * maxCoreNumPerExecutor``` --------------------------------------- Other small changes include change memoryPerSlave in ApplicationDescription to memoryPerExecutor, as "Slave" is overrided to represent both worker and executor in the documents... (we have some discussion on this before?)
