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.
