   Hi pan, thanks for reviewing! 
   
   The compression format of celeborn may be inconsistent with spark. But does 
celeborn client need to be compatible with common configurations like 
spark.shuffle.compress?
   
   For example, my sparkapp is configured with spark.shuffle.compress=false but 
celeborn still compresses the shuffle data, which is beyond my expectation.
