Jaimin D Jetly commented on AMBARI-3555:
----------------------------------------
The patch adds one more manual command in the manual step of the wizard:
_"sudo su -l hdfs -c 'hdfs zkfc -formatZK' "_
This also removes stop namenode command from step-4 which was introduced as a
requirement in AMBARI-3526.
> Reassign Master (namenode HA): HDFS service check fails when standby namenode
> is stopped before wizard

> HDFS service check fails due to stale information preserved in zookeeper. We
> need to clear automatic failover information in zookeeper by adding a manual
> command. Also if this is done then we don't need to make sure that the
> namenode that is moved is in standby state by stopping namenode initially.
