----------------------------------
Summary: Bring back ShuffledHashJoin
Key: SPARK-13977
URL: https://issues.apache.org/jira/browse/SPARK-13977
Project: Spark
Issue Type: Task
Components: SQL
Reporter: Davies Liu
Assignee: Davies Liu
ShuffledHashJoin is still useful when:
1) any partition of the build side could fit in memory
2) the build side is much smaller than stream side, the building hash table on
smaller side should be faster than sorting the bigger side.
