Andrew Purtell commented on HBASE-17069:
----------------------------------------
TRACE logging really slows everything down. The test has been running for ~24
hours, is not finished yet, has not reproduced the problem. The timing is off
and we are always winning the race instead of occasionally losing. Will redo
with DEBUG level logging next week after the holiday.

> Issue Type: Bug
> Affects Versions: 1.2.4
> Reporter: Andrew Purtell
> Priority: Critical
> Attachments: daughter_1_d55ef81c2f8299abbddfce0445067830.log,

> I have been seeing frequent ITBLL failures testing various versions of 1.2.x.
> Over the lifetime of 1.2.x the following issues have been fixed:
> - HBASE-15315 (Remove always set super user call as high priority)
> - HBASE-16093 (Fix splits failed before creating daughter regions leave meta
> inconsistent)
> And this one is pending:
> - HBASE-17044 (Fix merge failed before creating merged region leaves meta
> inconsistent)
> I can apply all of the above to branch-1.2 and still see this failure:
