viirya opened a new pull request #24757: [SPARK-27873][SQL] columnNameOfCorruptRecord should not be checked with column names in CSV header when disabling enforceSchema
URL: https://github.com/apache/spark/pull/24757
 
 
   ## What changes were proposed in this pull request?
   
   If we want to keep corrupt record when reading CSV, we provide a new column into the schema, that is `columnNameOfCorruptRecord`. But this new column isn't actually a column in CSV header. So if `enforceSchema` is disabled, `CSVHeaderChecker` throws a exception complaining that number of column in CSV header isn't equal to that in the schema.
   
   ## How was this patch tested?
   
   Added test.
