--------------------------------------

             Summary: Avoid re-creation of EvenColumnNameConverter in HBaseTimelineWriterImpl#storeEvents
                 Key: YARN-5235
                 URL: https://issues.apache.org/jira/browse/YARN-5235
             Project: Hadoop YARN
          Issue Type: Sub-task
          Components: timelineserver
    Affects Versions: YARN-2928
            Reporter: Joep Rottinghuis
            Assignee: Joep Rottinghuis
            Priority: Trivial


As per discussion in YARN-5052 [~varun_saxena] noted:
bq. In HBaseTimelineWriterImpl#storeEvents, we iterate over all events in a loop and will be creating EventColumnNameConverter object each time. Although its not a very heavy object right now, but can't we just create it once outside the loop ?
