             Summary: Should use defaults when missing JMX port info from configuration 
                 Key: AMBARI-1443
                 URL: https://issues.apache.org/jira/browse/AMBARI-1443
             Project: Ambari
          Issue Type: Bug
            Reporter: Tom Beerbower
            Assignee: Tom Beerbower
             Fix For: 1.2.2


There was a recent change to get JMX port information from configuration rather than use hard coded values.  It looks like it is possible that the port information may be missing or incomplete.  I see the following ...
{code}
{JOBTRACKER=50030, HBASE_MASTER=null, NAMENODE=50070, TASKTRACKER=null, DATANODE=50075}
{code}

Note the missing port values for HBASE_MASTER and TASKTRACKER.  In this case we will not show any JMX metrics for those components.

We should use the default values when the JMX port values are not available from configuration.

|NAMENODE|50070
|DATANODE|50075
|JOBTRACKER|50030
|TASKTRACKER|50060
|HBASE_MASTER|60010
