Review Comment:
   I think based on an earlier comment, this was moved here. However, I think 
we should write to db when we update the state that the partition is finalized. 
When a particular reduce partition fails to finalize, we don't add it to the 
result. However, we still mark the shuffle to be finalized. In that case we 
should update the database there as well.
