-----------------------------------

             Summary: Add ability to migrate/add/remove Storm Master components in order to
decommission host
                 Key: AMBARI-6676
                 URL: https://issues.apache.org/jira/browse/AMBARI-6676
             Project: Ambari
          Issue Type: Improvement
    Affects Versions: 1.6.1
         Environment: Hortonworks HDP 2.1 deployed via Ambari 1.6.1
            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?
