      Description

      The HiveLockManager interface defines the following method:

      public List<HiveLock> lock(List<HiveLockObj> objs,
      boolean keepAlive) throws LockException;

      ZooKeeperHiveLockManager implements HiveLockManager, but the current implementation of the "lock" method never actually references the "keepAlive" parameter. As a result, all of the locks acquired by the "lock" method are ephemeral. In other words, Zookeeper-based locks only exist as long as the underlying Zookeeper session exists. As soon as the Zookeeper session ends, any Zookeeper-based locks are automatically released.
