> As noted in HIVE-718, it can be tough to avoid race conditions when multiple clients
are trying to move files into the same directory. This patch adds a get_unique_id() call to
the metastore that returns the current value from an incrementing JDO Sequence so that clients
can avoid some races without locks.
