--------------------------------
Summary: Nested column pruning should retain column metadata
Key: SPARK-35232
URL: https://issues.apache.org/jira/browse/SPARK-35232
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 3.2.0
Reporter: Chao Sun
It seems we should retain column metadata when pruning nested columns.
Otherwise the info will be lost and will affect things such as re-constructing
CHAR/VARCHAR type (SPARK-33901).
