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

             Summary: Higher MAXCOLUMNS value in load DML options is leading to out of memory error
                 Key: CARBONDATA-247
                 URL: https://issues.apache.org/jira/browse/CARBONDATA-247
             Project: CarbonData
          Issue Type: Bug
            Reporter: dhatchayani
            Priority: Minor


When a higher value lets say Integer max value is configured for maxcolumns option in load DML and executor memory is less, then in that case UnivocityCsvParser throws an out of memory error when it tries to create an array of size of maxColumns option value.
