> In YARN-2264, a race in DrainDispatcher was fixed. Unfortunately, it also
> exists in AsyncDispatcher but wasn't found. In YARN-2991, another
> DrainDispatcher bug was fixed by letting DrainDispatcher extend
> AsyncDispatcher 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).
