Hyukjin Kwon created SPARK-33091:
------------------------------------
Summary: Avoid using map instead of foreach to avoid potential
side effect at OrcUtils.readCatalystSchema
Key: SPARK-33091
URL: https://issues.apache.org/jira/browse/SPARK-33091
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 3.0.1, 3.1.0
Reporter: Hyukjin Kwon
This is a kind of a followup of SPARK-32646. New JIRA was filed to control the
fixed versions properly.
When you use {{map}}, it might be lazily evaluated and not executed. To avoid
this, we should better use {{foreach}}.
