[jira] [Reopened] (AMBARI-13856) Sometimes when HA is enabled
NameNode does not wait to leave safe mode on start
[ https://issues.apache.org/jira/browse/AMBARI-13856?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Andrew Onischuk reopened AMBARI-13856:
--------------------------------------
Seems like we hit some problems with this patch. Sometimes NN cannot leave safemode when DNs are down. Which is the case for NN HA enable wizard.
I reverted this patch for now, we wll have to fix the ordering on UI first, and than commit this.
