> Standalone failure tests.

> Key: SAMZA-1748
> URL: https://issues.apache.org/jira/browse/SAMZA-1748
> Project: Samza
> Issue Type: New Feature
> Reporter: Shanthoosh Venkataraman
> Assignee: Shanthoosh Venkataraman
> Priority: Major
>
> In the standalone model, a processor can leave and join the group at any
> point in time.
> This processor reshuffle is referred to as rebalancing which results in
> task(work) redistribution amongst other available, live processors in the
> group.
> Processor rebalancing in existing standalone integration tests(junit tests)
> is accomplished through clean shutdown of the processors.
> However, in real production scenarios, processor rebalancing is triggered
> through unclean shutdown and full garbage collection(GC) of the processors.
> As a part of this JIRA, a failure test suite covering these production like
> scenarios will be added.
> Failure test suite will be built using the zopkio test framework and will
> cover the following test cases:
> 1. Force killing the leader processor of the group.
> 2. Force killing a single follower in the group.
> 3. Force killing multiple followers in the group.
> 4. Force killing the leader and a follower in the group.
> 5. Suspending and resuming the leader of the group.
> Since existing standalone integration tests cover event
> consumption/production after a rebalancing phase, these new tests will just
> test the coordination. We'll iterate on this initial suite and add tests
> whenever necessary.
