stack commented on HBASE-2231:
------------------------------
[~sershe] Sorry. Owe you response. Need to restudy patch and reconstitute
context. HBASE-2645 is related. Writer over there gets stuck on a sync and
eventually fails complaining about lease. Would think we'd see similar over
here when we try to write the compaction edit to the WAL on the dying
regionserver.
> Compaction events should be written to HLog

> The sequence for a compaction should look like this:
> # Compact region to "new" files
> # Write a "Compacted Region" entry to the HLog
> # Delete "old" files
> This deals with a case where the RS has paused between step 1 and 2 and the
> regions have since been reassigned.
