> There is an issue in ZooKeeperHiveLockManager.java, in which when locking exclusively on an object we didn't check if the children are locked.
> So the following should not be allowed.
> {noformat}
> use default; 
> lock table lockneg2.tstsrcpart shared; 
> lock database lockneg2 exclusive;
> {noformat}
> Also check the test case lockneg_try_lock_db_in_use.q to add more reasonable failure cases.
