[jira] [Created] (SPARK-42359) Support row skipping when reading CSV files

Willi Raschkowski created SPARK-42359:
-----------------------------------------

             Summary: Support row skipping when reading CSV files
                 Key: SPARK-42359
                 URL: https://issues.apache.org/jira/browse/SPARK-42359
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 3.3.1
            Reporter: Willi Raschkowski


Spark currently can't read CSV files that contain lines with comments or annotations above the header and data. Work-arounds include pre-processing CSVs, or using RDDs and something like {{zipWithIndex}}. But all of these increase friction for less technical users.

This issue proposes a {{skipLines}} option for Spark's CSV parser to drop a number of unwanted lines at the top of a CSV file.
