* [SPARK-6955] Perform port retries at NettyBlockTransferService levelAaron Davidson2015-05-081-36/+9
| | | | | | | | | | | | | Currently we're doing port retries in the TransportServer level, but this is not specified by the TransportContext API and it has other further-reaching impacts like causing undesirable behavior for the Yarn and Standalone shuffle services.

* [SPARK-6229] Add SASL encryption to network library.Marcelo Vanzin2015-05-0117-61/+986
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are two main parts of this change: - Extending the bootstrap mechanism in the network library to add a server-side bootstrap (which works a little bit differently than the client-side bootstrap), and to allow the bootstraps to modify the underlying channel. - Use SASL to encrypt data going through the RPC channel. The second item requires some non-optimal code to be able to work around the fact that the outbound path in netty is not thread-safe, and ordering is very important when encryption is in the picture. A lot of the changes outside the network/common library are just to adjust to the changed API for initializing the RPC server.

* [SPARK-7003] Improve reliability of connection failure detection between ↵Aaron Davidson2015-04-207-18/+375
| | | | | | | | | | | | | | | | | Netty block transfer service endpoints Currently we rely on the assumption that an exception will be raised and the channel closed if two endpoints cannot communicate over a Netty TCP channel. However, this guarantee does not hold in all network environments, and [SPARK-6962](https://issues.apache.org/jira/browse/SPARK-6962) seems to point to a case where only the server side of the connection detected a fault. This patch improves robustness of fetch/rpc requests by having an explicit timeout in the transport layer which closes the connection if there is a period of inactivity while there are outstanding requests. NB: This patch is actually only around 50 lines added if you exclude the testing-related code.

* [SPARK-6578] [core] Fix thread-safety issue in outbound path of network library.Marcelo Vanzin2015-04-016-10/+359
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While the inbound path of a netty pipeline is thread-safe, the outbound path is not. That means that multiple threads can compete to write messages to the next stage of the pipeline. The network library sometimes breaks a single RPC message into multiple buffers internally to avoid copying data (see MessageEncoder). This can result in the following scenario (where "FxBy" means "frame x, buffer y"): T1 F1B1 F1B2 \ \ \ \ socket F1B1 F2B1 F1B2 F2B2 / / / / T2 F2B1 F2B2 And the frames now cannot be rebuilt on the receiving side because the different messages have been mixed up on the wire. The fix wraps these multi-buffer messages into a `FileRegion` object so that these messages are written "atomically" to the next pipeline handler.

* [SPARK-4187] [Core] Switch to binary protocol for external shuffle service ↵Aaron Davidson2014-11-076-55/+107
| | | | | | | | | | | | | | | | | | 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.

* [SPARK-3796] Create external service which can serve shuffle filesAaron Davidson2014-11-0114-41/+146
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

* [SPARK-3453] Netty-based BlockTransferService, extracted from Spark coreReynold Xin2014-10-2945-0/+3710
This PR encapsulates #2330, which is itself a continuation of #2240. The first goal of this PR is to provide an alternate, simpler implementation of the ConnectionManager which is based on Netty. In addition to this goal, however, we want to resolve [SPARK-3796](https://issues.apache.org/jira/browse/SPARK-3796), which calls for a standalone shuffle service which can be integrated into the YARN NodeManager, Standalone Worker, or on its own. This PR makes the first step in this direction by ensuring that the actual Netty service is as small as possible and extracted from Spark core. Given this, we should be able to construct this standalone jar which can be included in other JVMs without incurring significant dependency or runtime issues. The actual work to ensure that such a standalone shuffle service would work in Spark will be left for a future PR, however. In order to minimize dependencies and allow for the service to be long-running (possibly much longer-running than Spark, and possibly having to support multiple version of Spark simultaneously), the entire service has been ported to Java, where we have full control over the binary compatibility of the components and do not depend on the Scala runtime or version. These issues: have been addressed by folding in #2330: SPARK-3453: Refactor Netty module to use BlockTransferService interface SPARK-3018: Release all buffers upon task completion/failure SPARK-3002: Create a connection pool and reuse clients across different threads SPARK-3017: Integration tests and unit tests for connection failures SPARK-3049: Make sure client doesn't block when server/connection has error(s) SPARK-3502: SO_RCVBUF and SO_SNDBUF should be bootstrap childOption, not option SPARK-3503: Disable thread local cache in PooledByteBufAllocator TODO before mergeable: - [x] Implement uploadBlock() - [x] Unit tests for RPC side of code - [x] Performance testing (see comments [here](https://github.com/apache/spark/pull/2753#issuecomment-59475022)) - [x] Turn OFF by default (currently on for unit testing) Author: Reynold Xin <rxin@apache.org> Author: Aaron Davidson <aaron@databricks.com> Author: cocoatomo <cocoatomo77@gmail.com> Author: Patrick Wendell <pwendell@gmail.com> Author: Prashant Sharma <prashant.s@imaginea.com> Author: Davies Liu <davies.liu@gmail.com> Author: Anand Avati <avati@redhat.com> Closes #2753 from aarondav/netty and squashes the following commits: cadfd28 [Aaron Davidson] Turn netty off by default d7be11b [Aaron Davidson] Turn netty on by default 4a204b8 [Aaron Davidson] Fail block fetches if client connection fails 2b0d1c0 [Aaron Davidson] 100ch 0c5bca2 [Aaron Davidson] Merge branch 'master' of https://github.com/apache/spark into netty 14e37f7 [Aaron Davidson] Address Reynold's comments 8dfcceb [Aaron Davidson] Merge branch 'master' of https://github.com/apache/spark into netty 322dfc1 [Aaron Davidson] Address Reynold's comments, including major rename e5675a4 [Aaron Davidson] Fail outstanding RPCs as well ccd4959 [Aaron Davidson] Don't throw exception if client immediately fails 9da0bc1 [Aaron Davidson] Add RPC unit tests d236dfd [Aaron Davidson] Remove no-op serializer :) 7b7a26c [Aaron Davidson] Fix Nio compile issue dd420fd [Aaron Davidson] Merge branch 'master' of https://github.com/apache/spark into netty-test 939f276 [Aaron Davidson] Attempt to make comm. bidirectional aa58f67 [cocoatomo] [SPARK-3909][PySpark][Doc] A corrupted format in Sphinx documents and building warnings 8dc1ded [cocoatomo] [SPARK-3867][PySpark] ./python/run-tests failed when it run with Python 2.6 and unittest2 is not installed 5b5dbe6 [Prashant Sharma] [SPARK-2924] Required by scala 2.11, only one fun/ctor amongst overriden alternatives, can have default argument(s). 2c5d9dc [Patrick Wendell] HOTFIX: Fix build issue with Akka 2.3.4 upgrade. 020691e [Davies Liu] [SPARK-3886] [PySpark] use AutoBatchedSerializer by default ae4083a [Anand Avati] [SPARK-2805] Upgrade Akka to 2.3.4 29c6dcf [Aaron Davidson] [SPARK-3453] Netty-based BlockTransferService, extracted from Spark core f7e7568 [Reynold Xin] Fixed spark.shuffle.io.receiveBuffer setting. 5d98ce3 [Reynold Xin] Flip buffer. f6c220d [Reynold Xin] Merge with latest master. 407e59a [Reynold Xin] Fix style violation. a0518c7 [Reynold Xin] Implemented block uploads. 4b18db2 [Reynold Xin] Copy the buffer in fetchBlockSync. bec4ea2 [Reynold Xin] Removed OIO and added num threads settings. 1bdd7ee [Reynold Xin] Fixed tests. d68f328 [Reynold Xin] Logging close() in case close() fails. f63fb4c [Reynold Xin] Add more debug message. 6afc435 [Reynold Xin] Added logging. c066309 [Reynold Xin] Implement java.io.Closeable interface. 519d64d [Reynold Xin] Mark private package visibility and MimaExcludes. f0a16e9 [Reynold Xin] Fixed test hanging. 14323a5 [Reynold Xin] Removed BlockManager.getLocalShuffleFromDisk. b2f3281 [Reynold Xin] Added connection pooling. d23ed7b [Reynold Xin] Incorporated feedback from Norman: - use same pool for boss and worker - remove ioratio - disable caching of byte buf allocator - childoption sendbuf/receivebuf - fire exception through pipeline 9e0cb87 [Reynold Xin] Fixed BlockClientHandlerSuite 5cd33d7 [Reynold Xin] Fixed style violation. cb589ec [Reynold Xin] Added more test cases covering cleanup when fault happens in ShuffleBlockFetcherIteratorSuite 1be4e8e [Reynold Xin] Shorten NioManagedBuffer and NettyManagedBuffer class names. 108c9ed [Reynold Xin] Forgot to add TestSerializer to the commit list. b5c8d1f [Reynold Xin] Fixed ShuffleBlockFetcherIteratorSuite. 064747b [Reynold Xin] Reference count buffers and clean them up properly. 2b44cf1 [Reynold Xin] Added more documentation. 1760d32 [Reynold Xin] Use Epoll.isAvailable in BlockServer as well. 165eab1 [Reynold Xin] [SPARK-3453] Refactor Netty module to use BlockTransferService.
