Subject [jira] [Reopened] (AMBARI-13856) Sometimes when HA is enabled NameNode does not wait to leave safe mode on start
Date Tue, 17 Nov 2015 06:45:11 GMT

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.
