Cheng Su created SPARK-32505:
--------------------------------

             Summary: Only codegen build side separately for shuffled hash join
                 Key: SPARK-32505
                 URL: https://issues.apache.org/jira/browse/SPARK-32505
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 3.1.0
            Reporter: Cheng Su


Currently `ShuffledHashJoinExec` needs to do code-gen separately for its both children per reason in [https://github.com/apache/spark/pull/29277#discussion_r463415144] . Creating this Jira as a followup, to only code-gen build side separately, but not stream side. Seeing above discussion for known blockers.
