Todd Lipcon commented on HBASE-2447:
------------------------------------
Yea, but that hflush improvement is still reasonably experimental, I think. I
think we ought to commit this first, and if we commit the other patch later
that's fine.
> LogSyncer.addToSyncQueue doesn't check if syncer is still running before

>
> In testing GC pause scenarios with kill -STOP, I got the regionserver into a
> situation where it was blocked forever while shutting down (also blocking
> clients, since the RPCs were still pinging). The root issue is that, if the
> log syncer has an error just as more edits are being done, addToSyncQueue()
> can go to sleep waiting on a syncer which has just died.
