> 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
> Priority: Minor
>
> 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
