[GitHub] flink pull request #5309: [FLINK-8450] [flip6] Make JobMaster/DispatcherGate...
GitHub user tillrohrmann opened a pull request:
https://github.com/apache/flink/pull/5309
[FLINK-8450] [flip6] Make JobMaster/DispatcherGateway#requestJob type safe
## What is the purpose of the change
Let JobMasterGateway#requestJob and DispatcherGateway#requestJob return a
CompletableFuture<SerializableExecutionGraph> instead of a
CompletableFuture<AccessExecutionGraph>. In order to support the old code
and the JobManagerGateway implementation we have to keep the return type
in RestfulGateway. Once the old code has been removed, we should change
this as well.
## Brief change log
- Change return type of `RestfulGateway#requestJob` to `CompletableFuture<? extends AccessExecutionGraph>`
- Change return type of `JobMasterGateway#requestJob` and `DispatcherGateway#requestJob` to `CompletableFuture<SerializableExecutionGraph>`
- Introduce `TestingRestfulGateway` as a testing utility
- Adapt `ExecutionGraphCacheTest` to use `TestingRestfulGateway` instead of Mockito mocks
## Verifying this change
This change is already covered by existing tests.
## Does this pull request potentially affect one of the following parts:
- Dependencies (does it add or upgrade a dependency): (no)
- The public API, i.e., is any changed class annotated with `@Public(Evolving)`: (no)
- The serializers: (no)
- The runtime per-record code paths (performance sensitive): (no)
- Anything that affects deployment or recovery: JobManager (and its components), Checkpointing, Yarn/Mesos, ZooKeeper: (no)
- The S3 file system connector: (no)
## Documentation
- Does this pull request introduce a new feature? (no)
- If yes, how is the feature documented? (not applicable)

commit 9883bed1cca16a419a46fe09ad1498ada42d67e2
Author: Till Rohrmann <tr...@...>
Date: 2018-01-16T17:45:53Z
[FLINK-8449] [flip6] Extend OnCompletionActions to accept an SerializableExecutionGraph
This commit introduces the SerializableExecutionGraph which extends the
AccessExecutionGraph and adds serializability to it. Moreover, this commit
changes the OnCompletionActions interface such that it accepts a
SerializableExecutionGraph instead of a plain JobResult. This allows to
archive the completed ExecutionGraph for further usage in the container
component of the JobMasterRunner.

Wouldn't it be easier to make `CountingRestfulGateway` thread safe, and reuse it here?

Yes you're right @zentol. Thanks for the pointer. Will remove `DummyExecutionGraph` and its builder and replace it with `ArchivedExecutionGraphBuilder`.

You can reassign `accessExecutionGraphFuture` to avoid `2`. I don't think `2` is adding anything to the readability.
