> Affects Versions: 1.4.2
> Reporter: Aleksandr Kovalenko
> Assignee: Aleksandr Kovalenko
> Fix For: 1.4.2

> Attachments: AMBARI-3538.patch, Empty host pop-up.png

>
> There are API calls which do not generate tasks on server and web-client
> doesn't poll them. We should not show empty host pop-up for such command
> (Empty host pop-up.png).
> *For NameNode HA setup:*
> Step-4 (Install, Start and Test) has following commands whose link on the
> label to host pop-up should be disabled
> * NameNode + ZKFC create
> * NameNode + ZKFC disable
> * NameNode + ZKFC reconfigure
> Step-6 (Install, Start and Test) has NameNode+ZKFC remove command whose link
> on the label should be disabled.
> Similarly please revisit reassign master wizard for other components and
> remove label link to host popup for the commands that do not trigger API call
> which returns request id that needs to be polled for progress.
