[jira] [Created] (SPARK-40076) Support number-only column names in ORC data sources when orc impl is hive

mcdull_zhang created SPARK-40076:
------------------------------------

             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
