    Description

      JobTrackerMetricsInst.doUpdates updates job-level counters of all running jobs into JobTracker's metrics causing very bad performance and hampers heartbeats. Since Job level metrics are better served by JobHistory, it may be a good idea to remove these from the metrics framework.
