Todd Lipcon commented on HBASE-2231:
------------------------------------
I'm going to suck it up and take this one on, I think - it's fairly easy to
reproduce by doing heavy writes with WAL disabled for those writes, and then
kill -STOP a region server for 65 seconds or so.
> Compaction events should be written to HLog

> Key: HBASE-2231
> URL: https://issues.apache.org/jira/browse/HBASE-2231
> Project: Hadoop HBase
> Issue Type: Improvement
> Components: regionserver
> Reporter: Todd Lipcon
> Assignee: Todd Lipcon
>
> 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.
