Review request for Ambari, Alejandro Fernandez and Sid Wagle.


Bugs: AMBARI-11762
    https://issues.apache.org/jira/browse/AMBARI-11762


Repository: ambari


Description
-------

The HDFS status summary still shows "no alerts" even when the ZKFC is down.  
Please see screen shots attached. 

Looking inside the "zookeeper failover controller process", it is monitoring if 
port 2181 is open. It seems the configuration key is defined is wrong.

Testing
-------

Verified that the new alerts worked with the ZKFC; monitored the ZKFC log to 
ensure there were no exceptions as a result of the TCP connection


Thanks,

Jonathan Hurley
