Hyukjin Kwon resolved SPARK-30249.
----------------------------------
Resolution: Not A Problem
> Invalid Column Names in parquet tables should not be allowed
> ------------------------------------------------------------
>
> Key: SPARK-30249
> URL: https://issues.apache.org/jira/browse/SPARK-30249
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.0.0
> Reporter: Rakesh Raushan
> Priority: Minor
>
> Column names such as `a:b` , `??`, `,,`, `^^` , `++`etc are allowed when we are creating parquet tables.
> While when we are creating tables with `orc` all such column names are marked as invalid and analysis exception is thrown.
> These column names should also be not allowed for parquet tables as well.
> Also this induces inconsistency between column names for Parquet and ORC
