    Description

      We borrowed Hadoop's JvmPauseMonitor some time ago. On HADOOP-14960 (Add GC time percentage monitor/alerter), Hadoop added a new GcTimeMonitor, which seems useful:

      /**
 * This class monitors the percentage of time the JVM is paused in GC within
 * the specified observation window, say 1 minute. The user can provide a
 * hook which will be called whenever this percentage exceeds the specified
 * threshold.
 */
