   > I heard from @jerqi that the range partition should be removed in the 
future.
   
   Yeah, maybe. If more experiments are done and we find range partition cannot 
merge small I/Os effectively. Then, we can remove range partition for sure.

   For example, shuffle-server-1 has the HDD, but shuffle-server-2 uses the 
SSD. We could make single app use the same local storage to avoid w/r speed gap.
   
   Mixed storage deployment in single uniffle cluster is also on the table. I 
will open a new issue to describe this scenario. I believe mixed deployments, 
especially SSD shuffle workers would be beneficial for high priority and valued 
spark/mr applications.
