Matt Martin updated HIVE-3533:
------------------------------

    Attachment: HIVE-3533.1.patch.txt

Uploading the very simple patch for this issue.  Replacing the hardcoded value of "false"
with the boolean parameter "keepAlive".

> 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.
