> 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.
