Lars Hofhansl updated HBASE-12457:
----------------------------------
Attachment: 12457.interrupt.txt
Like this...? (Pretty, needs to be cleaned up with APIs, etc, but shows what I
mean).
This should cause any IO in the Compactor to throw an InterruptedIOException,
which will (should, need to verify) abort the compaction immediately. That is
OK, as we are abandoning the compaction anyway.
> Regions in transition for a long time when CLOSE interleaves with a slow
> compaction

>
> 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.
