[jira] [Created] (HIVE-12415) Add command to show all locks in Hive

---------------------------------

             Summary: Add command to show all locks in Hive 
                 Key: HIVE-12415
                 URL: https://issues.apache.org/jira/browse/HIVE-12415
             Project: Hive
          Issue Type: New Feature
          Components: Locking, SQL
    Affects Versions: 1.2.1
            Reporter: Lenni Kuff


Customers often have lock conflicts in Hive. Currently we can use {{show locks extend}} command to show the existing locks on an object (db, table or partition) if it is know. However, some customers want to show all the locks over Hive service for monitoring purpose. It would be useful to add a new statement in Hive to support this.
To reduce noise, it might be useful to add an option to only show locks that have existed > N minutes.
