> PROBLEM:  Use Ambari 1.5.1, and upgrade HDP stack to 2.1 with Namenode HA enable, at
step 7 of http://docs.hortonworks.com/HDPDocuments/Ambari-1.5.1.0/bk_upgrading_Ambari/content/ch02s03.html.
When try to restart HDFS, zkfc is not able to start due to ha.zookeeper.quorum is missing
in core-site.xml. And NN fails to become active. The error in zkfc.log:
> Unable to start failover controller. Unable to connect to ZooKeeper quorum at klss20.test.com:2181,klss21.test.com:2181,klss22.test.com:2181.
Please check the configured value for ha.zookeeper.quorum and ensure that ZooKeeper is running.
> SUPPORT ANALYSIS: 
> The below setting should exists in core-site.xml:
> <property>
>       <name>ha.zookeeper.quorum</name>
>  <value>klss20.test.com:2181,klss21.test.com:2181,klss22.test.com:2181</value>
>     </property>
