Subject [jira] Created: (HIVE-789) Add get_unique_id() call to metastore
Date Mon, 24 Aug 2009 23:00:59 GMT
Add get_unique_id() call to metastore
-------------------------------------

                 Key: HIVE-789
                 URL: https://issues.apache.org/jira/browse/HIVE-789
             Project: Hadoop Hive
          Issue Type: Improvement
          Components: Metastore
            Reporter: Todd Lipcon
             Fix For: 0.4.0


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.
