[jira] [Created] (HIVE-8243) clone SparkWork for join optimization

Suhas Satish created HIVE-8243:
----------------------------------

             Summary: clone SparkWork for join optimization
                 Key: HIVE-8243
                 URL: https://issues.apache.org/jira/browse/HIVE-8243
             Project: Hive
          Issue Type: Bug
          Components: Spark
            Reporter: Suhas Satish


Map-join optimization needs to clone the SparkWork containing the operator tree to make changes to it. For MapredWork, this is done thru kryo serialization/deserialization in 
https://issues.apache.org/jira/browse/HIVE-5263

Something similar should be done for SparkWork
