[jira] [Created] (HIVE-18691) Drop Support for Explicit Table Lock From Apache Hive

BELUGA BEHR created HIVE-18691:
----------------------------------

             Summary: Drop Support for Explicit Table Lock From Apache Hive
                 Key: HIVE-18691
                 URL: https://issues.apache.org/jira/browse/HIVE-18691
             Project: Hive
          Issue Type: Improvement
          Components: HiveServer2
    Affects Versions: 3.0.0
            Reporter: BELUGA BEHR


The ability to explicitly lock a Hive table:

* Is not officially [documented|https://cwiki.apache.org/confluence/display/Hive/Locking]
* It's buggy [HIVE-10984] 
* Not implemented everywhere [HIVE-12285]

Please consider dropping this feature from Hive 3.0.  If applications need synchronization, allow them to do it externally, directly through something like ZooKeeper.
