> In YARN-2264, a race in DrainDispatcher was fixed. Unfortunately, it also
> exists in AsyncDispatcher (this was found and ignored in YARN-3878 but never
> documented...). In YARN-2991, another DrainDispatcher bug was fixed by
> letting DrainDispatcher reuse some AsyncDispatcher method because
> AsyncDispatcher doesn't have such issue. However, this shadows YARN-2264, and
> now similar race reappears in Tez unit tests (probably also YARN unit tests
> also).
