Siddharth Seth updated MAPREDUCE-4455:
--------------------------------------
Fix Version/s: (was: trunk)
Target Version/s: 2.2.0-alpha
Status: Open (was: Patch Available)
Mayank, these transitions don't seem to be valid. I got this wrong while
talking to you about this earlier... sorry about that.
The unit test is broken in this case. The InlineDispatcher, which is used for
this test and others, behaves differently from the regular dispatcher. It
handles all events inline, as against handling one event to completion before
processing the next one.
For this test - the App should have transitioned to the KILLED state, before
the ATTEMPT_KILLED event came in.
The DrainDispatcher seems like a much better option for unit tests.
> RMAppImpl state machine does not handle event ATTEMPT_KILLED at ACCEPTED

> TestRMAppTransitions#testAppSubmittedKilled causes an invalid event exception
> but the test doesn't catch the error since the final app state is still
> killed. Killed for the wrong reason, but the final state is the same.
