RE: Hive 0.7.1 with MySQL 5.5 as metastore
Hi Mark,
I just started to restore the data to a separate MySQL 5.1 schema, will try to create a table and post back here.
I copied the error stack trace below.

Venkatesh,What's the exact integrity constraint error you are seeing?
I'd be curious to see if you restored the data from the mysqldump onto a separate schema/db on MySQL 5.1 server whether you still get the error or not.

Sorry for the confusion, the problem is not with the MySQL version upgrade - I have indeed performed the upgrade by doing a mysqldump and restoring the data.
The problem is with how Hive 0.7.1 is interacting with the same metastore data on a different version of MySQL server.
