Description

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:

namenode:50070/jmx?qry=Hadoop:service=NameNode,name=NameNodeStatus

Returns:

    "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"
  } ]
}

In case of HDP 2.0.11, it returns:

{
  "beans" : [ ]
}
