Review request for Ambari, Andrew Onischuk and Vitalyi Brodetskyi.
Bugs: AMBARI-7925
https://issues.apache.org/jira/browse/AMBARI-7925
Repository: ambari
Description
-------
Initial analysis:
First namenode start attempt failed for me. Probably, that caused NN to enter
safe mode. After fixing perm gen memory size value, I've tried to start NN
again. Our stack scripts seem to move NN out of safe mode on start if needed.
But on HDP-2.2 stack, command for doing this is deprecated and fails with a
non-zero exit code.
