HeartSaVioR edited a comment on issue #27872: [SPARK-31115][SQL] Detect known Janino bug janino-compiler/janino#113 and apply workaround automatically as a fail-back via avoid using switch statement in generated code URL: https://github.com/apache/spark/pull/27872#issuecomment-599026718 Honestly I'm not sure about the details I got the proposal from @rednaxelafx - what I can imagine for only touching ExpandExec to get around is option 4 from my proposal, and if he meant other trick/technique than I don't get it. It would be nice if someone could help me understand via elaborating a bit.
