Review request for Ambari, Richard Zang, Srimanth Gunturi, and Yusaku Sako.


Bugs: AMBARI-12197
    https://issues.apache.org/jira/browse/AMBARI-12197


Repository: ambari


Description
-------

While adding a new service in kerberized cluster, we are using kerberos 
descriptor persisted at cluster resource endpoint. This kerberos descriptor has 
kerberos definition for all services present in the stack definition when 
kerberos wizard was executed.

When a kerberos supporting uninstalled service and non-existing in a stack of 
already kerberized cluster gets added later in the stack via HDP upgrade, Add 
service wizard triggered subsequently after upgrade to install that service 
will not show kerberos identities or configuration of that service for any user 
customizations. 

As part of this patch, new services properties are fetched from stack 
descriptor instead of cluster descriptor. Also all the kerberos realted 
configuration (identities and properties) of a service in the stack descriptor 
that are not present in the cluster descriptor are shown for customization and 
applied to the cluster.
