> Enable mapjoin hints [Spark Branch]
> -----------------------------------
>
> Key: HIVE-8911
> URL: https://issues.apache.org/jira/browse/HIVE-8911
> Project: Hive
> Issue Type: Sub-task
> Components: Spark
> Affects Versions: spark-branch
> Reporter: Szehon Ho
> Assignee: Chao
> Attachments: HIVE-8911.1-spark.patch, HIVE-8911.2-spark.patch,
> HIVE-8911.3-spark.patch, HIVE-8911.4-spark.patch, HIVE-8911.5-spark.patch,
> HIVE-8911.6-spark.patch
>
>
> Currently the big table selection in a mapjoin is based on stats.
> We should also enable the big-table selection based on hints. See class
> MapJoinProcessor. This is a logical-optimizer class, so we should be able to
> re-use this without too many changes to hook up with SparkMapJoinResolver.
