----------------------------------------
Summary: False alert on "NameNode High Availability Health" due to
Missing JMX objects
Key: AMBARI-12317
URL: https://issues.apache.org/jira/browse/AMBARI-12317
Project: Ambari
Issue Type: Bug
Components: ambari-server
Affects Versions: 2.0.0
Reporter: Jonathan Hurley
Assignee: Jonathan Hurley
Fix For: 2.1.0
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}
