Subject [jira] [Created] (HIVE-3133) Implement map-side non-equi join
Date Wed, 13 Jun 2012 18:33:43 GMT
Navis created HIVE-3133:
---------------------------

             Summary: Implement map-side non-equi join
                 Key: HIVE-3133
                 URL: https://issues.apache.org/jira/browse/HIVE-3133
             Project: Hive
          Issue Type: Improvement
            Reporter: Navis
            Priority: Minor


It's rather simple to implement non-equi join in mapjoin by replacing hashmap to treemap,
if it's targeted for single column. And if it's targeted two or more columns we can facilitate
lucene file for lookup in mapjoin operator.

I wish I could provide the patch but it's not my decision by contract. I believe someone can
implement this for public use.
