* [SPARK-10745][CORE] Separate configs between shuffle and RPCShixiong Zhu2015-11-186-6/+6
| | | | | | | | | | [SPARK-6028](https://issues.apache.org/jira/browse/SPARK-6028) uses network module to implement RPC. However, there are some configurations named with `spark.shuffle` prefix in the network module. This PR refactors them to make sure the user can control them in shuffle and RPC separately. The user can use `spark.rpc.*` to set the configuration for netty RPC. Author: Shixiong Zhu <shixiong@databricks.com> Closes #9481 from zsxwing/SPARK-10745.

* [SPARK-10004] [SHUFFLE] Perform auth checks when clients read shuffle data.Marcelo Vanzin2015-09-023-29/+152
| | | | | | | | | | | | | | | To correctly isolate applications, when requests to read shuffle data arrive at the shuffle service, proper authorization checks need to be performed. This change makes sure that only the application that created the shuffle data can read from it. Such checks are only enabled when "spark.authenticate" is enabled, otherwise there's no secure way to make sure that the client is really who it says it is.

* [SPARK-9439] [YARN] External shuffle service robust to NM restarts using leveldbImran Rashid2015-08-217-35/+286
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | https://issues.apache.org/jira/browse/SPARK-9439 In general, Yarn apps should be robust to NodeManager restarts. However, if you run spark with the external shuffle service on, after a NM restart all shuffles fail, b/c the shuffle service has lost some state with info on each executor. (Note the shuffle data is perfectly fine on disk across a NM restart, the problem is we've lost the small bit of state that lets us *find* those files.) The solution proposed here is that the external shuffle service can write out its state to leveldb (backed by a local file) every time an executor is added. When running with yarn, that file is in the NM's local dir. Whenever the service is started, it looks for that file, and if it exists, it reads the file and re-registers all executors there. Nothing is changed in non-yarn modes with this patch. The service is not given a place to save the state to, so it operates the same as before. This should make it easy to update other cluster managers as well, by just supplying the right file & the equivalent of yarn's `initializeApplication` -- I'm not familiar enough with those modes to know how to do that.

* [SPARK-6229] Add SASL encryption to network library.Marcelo Vanzin2015-05-014-17/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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-4187] [Core] Switch to binary protocol for external shuffle service ↵Aaron Davidson2014-11-0718-201/+501
| | | | | | | | | | | | | | | | | | 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-3796] Create external service which can serve shuffle filesAaron Davidson2014-11-0115-0/+1630
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).
