> Fix For: 1.0.0
>
>
> both FileSinkDesk and ReduceSinkDesk have special code path for Update/Delete
> operations. It is not always set correctly for ReduceSink.
> ReduceSinkDeDuplication is one place where it gets lost. Even when it isn't
> set correctly, elsewhere we set ROW_ID to be the partition column of the
> ReduceSinkOperator and UDFToInteger special cases it to extract bucketId from
> ROW_ID. We need to modify Explain Plan to record Write Type (i.e.
> insert/update/delete) to make sure we have tests that can catch errors here.
