Zhijie Shen commented on MAPREDUCE-5562:
----------------------------------------
Did some local tests for the latest patch.
1. Unregistration fails but the application still have chance to retry
according to the configuration. A new AM will be started, the client will not
show the final state until the second AM gets finished. The staging dir will
not be cleaned.
2. Unregistration fails but the application doesn't have the chance to retry
according to the configuration. No more AM will be started, the client will
show FAILED according to RM. The staging dir will be cleaned.
> MR AM should exit when unregister() throws exception
