Apache Spark commented on SPARK-42163: -------------------------------------- User 'cashmand' has created a pull request for this issue: https://github.com/apache/spark/pull/39718 > Schema pruning fails on non-foldable array index or map key > ----------------------------------------------------------- > > Key: SPARK-42163 > URL: https://issues.apache.org/jira/browse/SPARK-42163 > Project: Spark > Issue Type: Bug > Components: Optimizer > Affects Versions: 3.2.3 > Reporter: David Cashman > Priority: Major > > Schema pruning tries to extract selected fields from struct extractors. It > looks through GetArrayItem/GetMapItem, but when doing so, it ignores the > index/key, which may itself be a struct field. If it is a struct field that > is not otherwise selected, and some other field of the same attribute is > selected, then pruning will drop the field, resulting in an optimizer error. -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
