Hi Tian-Ying,

If the need is urgent, try out the solution from Shrijeet at
https://issues.apache.org/jira/browse/HBASE-643 (see my comment there
at around end). We tried it out earlier today for another purpose, and
it had a few hitches but nothing unfixable by "hbck -fix".

92 does not have it, we copied it from CDH3. However it does not work. I then found several
issues with it, and fixed them. We used it in our production cluster to rename some very big
tables. Even when the cluster was shutdown during the rename_table (test purpose), the script
will continue the rename and succeed if invoking the same rename command again after cluster
is back.

my patch.
