ryan rawson commented on HBASE-2231:
------------------------------------
The original plan seems good, or have things changed too much? If we can
piggypack on HLog, that would be better since as JD pointed out ZK can be
tricky.
Given that this issue is so small, should we hold up 0.90 for this or not?

> 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.
