   @bibhu107 and why shuffle data grow, I haven't looked at the code in detail; 
the following is just my guess. you have too much reducer, so the shuffle data 
may be need more meta. And on the other head, 0.7 -> 0.14, may be the shuffle's 
java object attr has change, this alse can cause diff. But I think parallelism 
is the major problem.
