Varun Saxena updated YARN-5911:
-------------------------------
Description:
DrainDispatcher#serviceStop sets the stopped flag first before draining the
event queue.
This means that the thread terminates as soon as it encounters stopped flag as
true and does not continue to process leftover events in queue, something which
it should do if setDrainEventsOnStop is set.
> DrainDispatcher does not drain all events on stop even if
> setDrainEventsOnStop is true
