Subject [jira] Created: (HIVE-300) DISTRIBUTE BY should support expressions
Date Mon, 23 Feb 2009 23:34:03 GMT
DISTRIBUTE BY should support expressions

                 Key: HIVE-300
                 URL: https://issues.apache.org/jira/browse/HIVE-300
             Project: Hadoop Hive
          Issue Type: Improvement
          Components: Query Processor
    Affects Versions: 0.2.0, 0.3.0
            Reporter: Zheng Shao

easy to allow expressions (while it will be hard for Sort By and Cluster By).

SELECT a.key, a.value FROM a
