Suhas Satish commented on HIVE-8243:
------------------------------------

cloning via kryo.copy() as suggested for MapredWork in https://issues.apache.org/jira/browse/HIVE-4396
maybe a good approach here.

> 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
