RE: status of bin/rename_table.rb

Our customers need to use rename_table to solve an issue in our production cluster. Since 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.

I think it is helpful to have rename_table script handy. I can open a jira and attach my patch.

Thanks
Tian-Ying

The script has gone stale.  It is removed in trunk and should have probably been removed earlier.

That said, its pretty basic what it does.  What sort of issues are you seeing?  Does running disable/enable help?
