there is no way for user to revert back and this check should be done in alter table function.
previous patch was relative ql instead of hive/trunk
Looks fine to me.
The error message though has a misspelling for column...
Can you fix that. I will check it in once that is done...
fixed the spelling mistake
some of the tests failed due to the change in the error message. Can you recapture and upload a new patch.
updated two test outputs to match the incorrect spelling
committed. Thanks Prasad!!
