Subject [jira] Created: (HIVE-1511) Hive plan serialization is slow
Date Wed, 04 Aug 2010 18:09:18 GMT
Hive plan serialization is slow
-------------------------------

                 Key: HIVE-1511
                 URL: https://issues.apache.org/jira/browse/HIVE-1511
             Project: Hadoop Hive
          Issue Type: Improvement
    Affects Versions: 0.7.0
            Reporter: Ning Zhang


As reported by Edward Capriolo:

For reference I did this as a test case....
SELECT * FROM src where
key=0 OR key=0 OR key=0 OR  key=0 OR key=0 OR key=0 OR key=0 OR key=0
OR key=0 OR key=0 OR key=0 OR
key=0 OR key=0 OR key=0 OR  key=0 OR key=0 OR key=0 OR key=0 OR key=0
OR key=0 OR key=0 OR key=0 OR
...(100 more of these)

No OOM but I gave up after the test case did not go anywhere for about
2 minutes.
