Ziting Shen created SPARK-57484:
-----------------------------------
Summary: ColumnarToRowExec can crash codegen when columnar data
contains unexpected nulls
Key: SPARK-57484
URL: https://issues.apache.org/jira/browse/SPARK-57484
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 3.5.8, 4.0.0
Reporter: Ziting Shen
{{ColumnarToRowExec may materialize null values from a columnar batch even when
the planned output attribute is non-nullable, so downstream row codegen can
skip null checks and fail with errors such as UTF8String.getBaseObject() NPEs.}}
