> Under heave load we have observed regions remaining in transition for 20
> minutes when the master requests a close while a slow compaction is running.
> The pattern is always something like this:
> # RS starts a compaction
> # HM request the region to be closed on this RS
> # Compaction is not aborted for another 20 minutes
> # The region is in transition and not usable.
> In every case I tracked down so far the time between the requested CLOSE and
> abort of the compaction is almost exactly 20 minutes, which is suspicious.
> Of course part of the issue is having compactions that take over 20 minutes,
> but maybe we can do better here.
