-----------------------------------
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?
