----------------------------------------

             Summary: Collision between HBase Master and RS metrics
                 Key: AMBARI-15250
                 URL: https://issues.apache.org/jira/browse/AMBARI-15250
             Project: Ambari
          Issue Type: Bug
          Components: ambari-metrics
    Affects Versions: 2.0.0
            Reporter: Siddharth Wagle
            Assignee: Siddharth Wagle
             Fix For: 2.2.2


Found out that Ganglia added the processName in JVM metrics to make this 
distinction::

org.apache.hadoop.metrics.ganglia.GangliaContext#emitRecord

{code}
// Setup so that the records have the proper leader names so they are
    // unambiguous at the ganglia level, and this prevents a lot of rework
    StringBuilder sb = new StringBuilder();
    sb.append(contextName);
    sb.append('.');

    if (contextName.equals("jvm") && outRec.getTag("processName") != null) {
      sb.append(outRec.getTag("processName"));
      sb.append('.');
    }
{code}

This is missing from our Sink which means some metrics do not have unique names 
and will collide. _Affects HBase only_
