[jira] [Created] (SPARK-3804) Output of Generator expressions is
not stable after serialization.
Michael Armbrust created SPARK-3804:
---------------------------------------
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.
