> The sorted shuffle avoidance can have some issues when the shuffle data gets 
> broken up into multiple chunks on disk.
> The 1-1 edge cannot skip the tez final merge - there's no reason for 1-1 to 
> have a final merge at all, it should open a single compressed file and write 
> a single index entry.
> Until the shuffle issue is resolved & a lot more testing, it is prudent to 
> disable the optimization for sorted shuffle edges and stop rewriting the 
> RS(sorted) = = = RS(sorted) into RS(sorted) = = = RS(FORWARD).
