             Summary: When ZooKeeperHiveLockManager locks an object 
exclusively, it doesn't check the lock on the children.
                 Key: HIVE-10984
                 URL: https://issues.apache.org/jira/browse/HIVE-10984
             Project: Hive
          Issue Type: Bug
          Components: Locking
            Reporter: Aihua Xu
            Assignee: Aihua Xu


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}
