Apache Spark reassigned SPARK-42163:
------------------------------------
Assignee: (was: Apache Spark)
> 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.
