> 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:
