Subject [jira] [Created] (AMBARI-15519) Add Service Wizard with nodes in the maintenance mode
Date Tue, 22 Mar 2016 20:09:25 GMT
Zhe (Joe) Wang created AMBARI-15519:
---------------------------------------

             Summary: Add Service Wizard with nodes in the maintenance mode
                 Key: AMBARI-15519
                 URL: https://issues.apache.org/jira/browse/AMBARI-15519
             Project: Ambari
          Issue Type: Bug
          Components: ambari-web
    Affects Versions: 2.4.0
            Reporter: Zhe (Joe) Wang
            Assignee: Zhe (Joe) Wang
             Fix For: 2.4.0


On the cluster where some nodes are in the maintenance mode Add Service Wizard doesn't track
this.
So, user may select host in the maintenance mode to install some master component. And this
component won't be installed (only record in the DB will be created for it).
Another situation:
there is some cluster where all nodes are in the maintenance mode. In this case ASW is almost
useless. Because all new components won't be installed while it works.

Maybe ASW should track hosts in the maintenance mode and warn user about adding components
on them (Steps "Assign Masters", "Assign Slaves and Clients")? Or just don't allow to do this?
