-------------------------------
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.
