------------------------------------
Summary: Support number-only column names in ORC data sources when
orc impl is hive
Key: SPARK-40076
URL: https://issues.apache.org/jira/browse/SPARK-40076
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 3.2.2
Reporter: mcdull_zhang
This problem is similar to SPARK-36663, both because
*CatalystSqlParser.parseDataType* fails to parse if a column name (and nested
field) consists of only numbers.
SPARK-36663solves the problem when configuring spark.sql.orc.impl=native
(default is native), but when configuring spark.sql.orc.impl=hive, it still
throws an error now
