Description

Our team operates 4000+ nodes hadoop cluster using apache ambari.
It is kerberized cluster.
More machines are getting into ambari cluster, more it is getting slower when deleting component.
I found that there are some unnecessary iterations when deleting component.
In order to be sure to remove keytab file, it checks all keytabs and principals in hosts with the same keytab path with the target.

I will soon make a pull request on github.com/apache/ambari.

Work around is not perfect. Just cancel all the "Prepare delete identities" operations on ambari web UI then you can do some other operations.
