Report Java VM metrics

                 Key: HADOOP-1562
                 URL: https://issues.apache.org/jira/browse/HADOOP-1562
             Project: Hadoop
          Issue Type: New Feature
          Components: metrics
            Reporter: David Bowen
            Assignee: David Bowen

It would be useful to have each Java process in Hadoop (JobTracker, TaskTracker, NameNode
and DataNode) report some Java VM metrics.  E.g. heap/non-heap memory used/committed, number
of garbage collections and percentage of time spent in GC, number of threads that are runnable/blocked/waiting/etc.
