      Description

      Both in the RM log and the NM log, I see the following exception thrown. First for RM,

      2016-05-16 14:19:29,930 ERROR org.apache.hadoop.yarn.server.timelineservice.collector.TimelineCollector: Error aggregating timeline metrics
      java.lang.NullPointerException

      In the NM log, I see a similar exception:
