I guess AMBARI-16828 is applied well for trunk, but there seems a mistake for
backporting the patch to branch-2.5. Please compare two links below:
For trunk:
https://github.com/apache/ambari/blob/trunk/ambari-metrics/ambari-metrics-storm-sink/src/main/java/org/apache/hadoop/metrics2/sink/storm/StormTimelineMetricsSink.java#L74
For branch-2.5:
https://github.com/apache/ambari/blob/branch-2.5/ambari-metrics/ambari-metrics-storm-sink/src/main/java/org/apache/hadoop/metrics2/sink/storm/StormTimelineMetricsSink.java#L74
