> Key: AMBARI-6676
> URL: https://issues.apache.org/jira/browse/AMBARI-6676
> Project: Ambari
> Issue Type: Improvement
> Affects Versions: 1.6.1
> Environment: HDP 2.1
> Reporter: Hari Sekhon
>
> Need ability in Ambari Web UI to migrate Storm Master components from one
> host to another in order to decomission host.
> There doesn't seem to be any option to add Nimbus, Storm REST API Server,
> Storm UI Server to another host or delete from the current host after
> stopping them and this prevents removal of the host with the usual type of
> message:
> "This host cannot be deleted since it has the following master components:
> Nimbus, Storm REST API Server, Storm UI Server
> To delete this host, you must first move all the master components listed
> above to another host."
> Except it doesn't appear the Ambari Web UI gives any method to do this. The
> Add drop down on other hosts doesn't give an option to add these components.
> I guess I'll have to go via the API. I saw the HBase Master jiras - I guess
> this means this add/remove component isn't done generically for any
> service/component?
> Regards,
