Sergey Shelukhin commented on HBASE-2231:
-----------------------------------------
Could it be related to the issue fixed in HBASE-7878, where recoverLease does
not really recover lease when splitting start when the lease is not recovered
yet, so due to timing data loss is possible? Or was it a different behavior
here on dead writer's side
> 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.
