> h3. When dimension is added in older versions like 1.1, by default it will be
> sort column. In sort step we assume data will be coming as sort column in the
> beginning. But the added column will be at last eventhough sort column. So,
> while building the dataload configurations for loading data, we rearrange the
> columns(dimensions and datafields) in order to bring the sort column to
> beginning and no-sort to last and revert them back to schema order before
> FinalMerge/DataWriter step.
> Issue:
> Data loading is failing because of castException in data writing step in
> case of NO_SORT and in final sort step in case of LOCAL_SORT.
