Review request for Ambari, Dmytro Sen, Mahadev Konar, Myroslav Papirkovskyy, and Yusaku Sako.


Bugs: AMBARI-8553
    https://issues.apache.org/jira/browse/AMBARI-8553


Repository: ambari


Description
-------

Installed a cluster without AMS / Ganglia
There are multiple problems.
After install phase of deployment is completed, UI gets stuck (see screenshot).  This is because
server throws 500 when UI makes a query against /api/v1/clusters/cluster/hosts?fields=Hosts/host_state,host_components/HostRoles/state
before proceeding to check for certain conditions.
At this point, even /api/v1/clusters/cluster throws 500.

The server log shows:


00:06:44,872  WARN [qtp1072019789-22] ServletHandler:514 - /api/v1/clusters/ys200
java.lang.NullPointerException
        at
