> HDP 2.0.11 produces an alert for NameNode HA. The script is making a call to jmx, which
works fine in HDP 2.2.0:
> {code}
> namenode:50070/jmx?qry=Hadoop:service=NameNode,name=NameNodeStatus
> {code}
> Returns:
> {code}
>     "name" : "Hadoop:service=NameNode,name=NameNodeStatus",
>     "modelerType" : "org.apache.hadoop.hdfs.server.namenode.NameNode",
>     "NNRole" : "NameNode",
>     "HostAndPort" : "cn030.l42scl.hortonworks.com:8020",
>     "SecurityEnabled" : true,
>     "State" : "active"
>   } ]
> }
> {code}
> In case of HDP 2.0.11, it returns: 
> {code}
> {
>   "beans" : [ ]
> }
> {code}
