---------------------------------
Summary: Modify SparkPlan generation to set toCache flag to
SparkTrans where caching is needed [Spark Branch]
Key: HIVE-8437
URL: https://issues.apache.org/jira/browse/HIVE-8437
Project: Hive
Issue Type: Sub-task
Components: Spark
Reporter: Xuefu Zhang
HIVE-8436 may modify the SparkWork right before SparkPlan generation. When this
happens, the output from some SparkTrans needs to be cached to avoid
regenerating the RDD. For more information, please refer to the design doc.
