> As per discussion in YARN-5170 [~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 ?
