> Implement bucket map join optimization [Spark Branch]
> -----------------------------------------------------
>
> Key: HIVE-8638
> URL: https://issues.apache.org/jira/browse/HIVE-8638
> Project: Hive
> Issue Type: Sub-task
> Components: Spark
> Reporter: Na Yang
> Assignee: Jimmy Xiang
> Fix For: spark-branch

> Attachments: HIVE-8638.1-spark.patch, HIVE-8638.2-spark.patch

>
> In the hive-on-mr implementation, bucket map join optimization has to depend
> on the map join hint. While in the hive-on-tez implementation, a join can be
> automatically converted to bucket map join if certain conditions are met such
> as:
> 1. the optimization flag hive.convert.join.bucket.mapjoin.tez is ON
> 2. all join tables are buckets and each small table's bucket number can be
> divided by big table's bucket number
> 3. bucket columns == join columns
> In the hive-on-spark implementation, it is ideal to have the bucket map join
> auto-convertion support. when all the required criteria are met, a join can
> be automatically converted to a bucket map join.
