Carl Steinbach updated HIVE-3133:
---------------------------------
Component/s: SQL
> Implement map-side non-equi join
> --------------------------------
>
> Key: HIVE-3133
> URL: https://issues.apache.org/jira/browse/HIVE-3133
> Project: Hive
> Issue Type: Improvement
> Components: Query Processor, SQL
> 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.
