Review request for Ambari and Sriharsha Chintalapani.


Bugs: AMBARI-17100
    https://issues.apache.org/jira/browse/AMBARI-17100


Repository: ambari


Description
-------

STR:
* Install Ambari 2.4
* Install HDP 2.4
* Kerberize the cluster
* Perform EU to HDP 2.5

The config packs have
<replace key="ui.filter" 
find="backtype.storm.security.auth.KerberosPrincipalToLocal"
                     
replace-with="org.apache.storm.security.auth.KerberosPrincipalToLocal" />

However, storm.yaml still has storm.principal.tolocal : 
'backtype.storm.security.auth.KerberosPrincipalToLocal'

I replaced that property as well and it started working.
Storm 1.0.1 already has its kerberos.json file using "storm.principal.tolocal": 
"org.apache.storm.security.auth.KerberosPrincipalToLocal", and stack HDP 2.5 
uses that version of Storm, so EU/RU should set the property if it exists, 
meaning the cluster is kerberized.

Testing (updated)
-------

Verified during EU from HDP 2.4 to 2.5 on a Kerberized cluster with Storm that 
the property was changed.


Thanks,

Alejandro Fernandez
