Zhijie Shen commented on YARN-296:
----------------------------------
The patch should work, but IMHO, the essential problem is that APP_ACCEPTED is
not expected at RUNNING. APP_ACCEPTED is created during ScheduleTransition of a
RMAppAttempt, and is consumed when a RMApp moves from SUBMITTED to ACCEPTED.
Only after the RMApp enters ACCEPTED, it can further move to RUNNING (similar
for UnmanagedAM). Therefore, APP_ACCEPTED shouldn't be seen when the RMApp is
at RUNNING.
Moreover, it seems impossible that APP_ACCEPTED belongs to the last
RMAppAttempt if the RMApp is retrying, as retry can only happen after the RMApp
enters ACCEPTED, where APP_ACCEPTED produced by the last RMAppAttempt has
already be consumed.
[~devaraj], would you mind post more context around the
InvalidStateTransitonException, such that we can dig more about the problem?
