[jira] [Commented] (SPARK-21619) Fail the execution of canonicalized plans explicitly

    [ https://issues.apache.org/jira/browse/SPARK-21619?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16113494#comment-16113494 ] 

Mark Hamstra commented on SPARK-21619:
--------------------------------------

Can you provide a little more context, Reynold, since on its face it would seem that if plans are to be blocked from executing based on their form, then non-canonical plans would be the ones that should be blocked.

> Canonicalized plans are not supposed to be executed. I ran into a case in which there's some code that accidentally calls execute on a canonicalized plan. This patch throws a more explicit exception when that happens.
