> Key: SPARK-27873
> URL: https://issues.apache.org/jira/browse/SPARK-27873
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.4.3
> Reporter: Marcin Mejran
> Assignee: Liang-Chi Hsieh
> Priority: Major
> Fix For: 3.0.0
>
>
> In the Spark CSV reader If you're using permissive mode with a column for storing corrupt records then you need to add a new schema column corresponding to columnNameOfCorruptRecord.
> However, if you have a header row and enforceSchema=false the schema vs. header validation fails because there is an extra column corresponding to columnNameOfCorruptRecord.
> Since, the FAILFAST mode doesn't print informative error messages on which rows failed to parse there is no way other to track down broken rows without setting a corrupt record column.
