Re: unbalanced transaction calls
If we can enable access logs on the meta store and figure out the last query before the one that failed, it should be easy to track it. I did find a couple of unbalanced calls in code. Will look more carefully and file a ticket.

Re: unbalanced transaction calls
Hi, This error is coming when we are running a CREATE TABLE script. Where are you suggesting we make these changes ?
