[jira] [Created] (AMBARI-7925) Namenode can not leave safe mode on
hdp-2.2 stack
Dmitry Lysnichenko created AMBARI-7925:
------------------------------------------
Summary: Namenode can not leave safe mode on hdp-2.2 stack
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
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.

Instead use the hdfs command for it.
