Chao updated HIVE-8622:
-----------------------
Attachment: HIVE-8622.4-spark.patch
Adopting Xuefu's pseudo code. Now for each BaseWork with MJ operator, use a
SparkWork for its parent BaseWorks that contain HashTableSinkOperator.
I manually tested this patch with several qfiles containing map-join queries,
and results look correct.
> Split map-join plan into 2 SparkTasks in 3 stages [Spark Branch]
