> Key: AMBARI-7925
> URL: https://issues.apache.org/jira/browse/AMBARI-7925
> Project: Ambari
> Issue Type: Bug
> Components: ambari-server
> Affects Versions: 1.7.0
> Environment: branch-1.7.0 122dae7
> stack HDP-2.2
> Reporter: Dmitry Lysnichenko
> Assignee: Dmitry Lysnichenko
> Fix For: 1.7.0

> Attachments: AMBARI-7925.patch, AMBARI-7925.patch.1

>
> 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.
