             Summary: Equal or lesser value of MAXCOLUMNS option than column count in CSV header results into array index of bound exception
                 Key: CARBONDATA-260
                 URL: https://issues.apache.org/jira/browse/CARBONDATA-260
             Project: CarbonData
          Issue Type: Bug
            Reporter: Manish Gupta
            Assignee: Manish Gupta


If column count in CSV header is more or equal to MAXCOLUMNS option value then array index out of bound exception is thrown by the Univocity CSV parser. This is because while parsing the row, parser adds each row to an array and increments the index and after incrementing it performs one more operation using the incremented index value which leads to array index pf bound exception
