     [ https://issues.apache.org/jira/browse/HBASE-2231?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Todd Lipcon updated HBASE-2231:
-------------------------------

    Fix Version/s:     (was: 0.90.0)
                   0.92.0

Setting to 0.92 but hope to get this in a dot release or later RC of 0.90 if 0.92 takes too long

> 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.
