---------------------------------------

             Summary: Output of Generator expressions is not stable after serialization.
                 Key: SPARK-3804
                 URL: https://issues.apache.org/jira/browse/SPARK-3804
             Project: Spark
          Issue Type: Bug
          Components: SQL
            Reporter: Michael Armbrust


The output of a generator expression (such as explode) can change after serialization.  This
caused a nasty data corruption bug.  While this bug has seen been addressed it would be good
to fix this since it violates the general contract of query plans.
