      Description

      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.
