Zhijie Shen updated MAPREDUCE-5562:
-----------------------------------
Attachment: MAPREDUCE-5562.5.patch
Created a patch according to Jason's suggestion. Basically we do the following
things:
1. Move the flag "successfulUnregistration" (which used to be
safeToReportTerminationToUser) to RMCommunicator#unregister, such that
cleaning the staging dir is able to be aware of this flag as well
2. The unregister fails, before cleaning the staging dir, we revisit
"isLastRetry" to see whether AM really doesn't have a chance or not. We only
clean the dir when no more retries are allowed according to the configured
maxAttempts.
3. Added the test case of cleaning the staging dir on unregister failure, and
modified the tests which are related to refactoring successfulUnregistration.
> MR AM should exit when unregister() throws exception
