Hyukjin Kwon commented on SPARK-30893: -------------------------------------- I am sure there are already multiple inconsistent instances out there. Probably some configurations would need more destructive fixes. Are they worthwhile? I am not sure. It seems to me a bit unlikely users set a different configurations that change behaviours between queries. For these data type related instances, they look easy to fix so probably fine for now. I am not so supportive of fixing other instances. > Expressions should not change its data type/behavior after it's created > ----------------------------------------------------------------------- > > Key: SPARK-30893 > URL: https://issues.apache.org/jira/browse/SPARK-30893 > Project: Spark > Issue Type: Bug > Components: SQL > Affects Versions: 3.0.0 > Reporter: Wenchen Fan > Priority: Critical > > This is a problem because the configuration can change between different > phases of planning, and this can silently break a query plan which can lead > to crashes or data corruption, if data type/nullability gets changed. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
