---------------------------------

             Summary: CSV default column names should be consistent
                 Key: SPARK-15274
                 URL: https://issues.apache.org/jira/browse/SPARK-15274
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 2.0.0
            Reporter: Andrew Or


If a column name is not provided, Spark SQL usually uses the convention "_c0", 
"_c1" etc., but when reading in CSV files without headers, we use "C0" and 
"C1". This is inconsistent and we should fix it by Spark 2.0.
