> After HIVE-1609, we are seeing some table not found errors intermittently.
> We have a test case where 5 processes are concurrently issueing the same query - 
> explain extended insert .. select from <T>
> and once in a while, we get a error <T> not found - 
> When we revert back the JDO version, the error is gone.
> We can investigate later to find the JDO bug, but for now this is a show-stopper for facebook, and needs
> to be reverted back immediately.
> This also means, that the filters will not be pushed to mysql.
