Devaraj K commented on MAPREDUCE-4841:
--------------------------------------
Sorry for the late response. Here AM is not crasing.
As Jason mentioned in the above comment, AM Attempt is failing to unregister
with RM due to restart of the NM where the AM launched and before unregister
first AM attempt is removing the staging directory. For the next AM attempts,
all are failing with FNFE due to staging files not present.
> Application Master Retries fail due to FileNotFoundException
