Description

https://github.com/apache/hive/blob/cbb9233a3b39ab8489d777fc76f0758c49b69bef/ql/src/java/org/apache/hadoop/hive/ql/exec/MoveTask.java#L233-L234

            LOG.info("about to release lock for output: {} lock: {}", output,
              lock.getHiveLockObject().getName());
            try {
              lockMgr.unlock(lock);
            } catch (LockException le) {

Change this to debug level logging. The lock manager's 'unlock' method should have additional logging available. Knowing that the unlock is about to take place is only helpful for debugging, not for normal operation.
