Feng Yuan commented on YARN-6277:
---------------------------------
[~kshukla],YARN-4095 could solve this.
But if ShuffleHandler could use the same Configuration object,i think will
solve this more gracefully and more flawless.
So now my choke point is why ShufflerHandler will use itself configuration when
initize.
