Ted Yu commented on HBASE-2231:
-------------------------------

Todd's patch is not small.
Now that HLog interface has been introduced, rebase is needed.

> 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.
