> problem:
> Currently in CarbonWriterBuilder,  
> sortColumnsList.indexOf(field.getFieldName()) return null due to case issue. so, one of the sortcolumns in array will be null. so one of the column schema becomes null,
> hence when column schema is accessed, we get NPE
> solution: Make sort columns as case insensitive..
> Change pareant column (as sort column is supported only foro parent columns) name to lower case when schema received by the user
> and change sort columns also to lower case when received by the user.
