Dave Latham updated HBASE-12891:
--------------------------------
Attachment: HBASE-12891-v4.1-0.98.patch
Ouch. My apologies in backporting the patch correctly. It wouldn't apply to
0.98 so I applied it by hand and missing a section of the code. Thanks Andrew
for your help, and very sorry about the mistakes. Thanks to Enis for detecting
the issue. Always a good reminder about the value of the tests.
Attaching "HBASE-12891-v4.1-0.98.patch" which is should fix the backport and
the test. TestHBaseFsck passes for me locally, and I'm hoping the HadoopQA bot
will successfully pick this one up.

> cluster to do this check in parallel to speed things up. I'll attach the
