I tested this locally and verified the serialization reduction. I posted 
the shuffle size comparison diagram in the PR description. I will merge this 
into master. Thanks for your review! @dbtsai @sethah

LGTM. Will be nice to see the compassion of shuffle write size, and then 
will be ready to merge. Thanks.

@yanboliang Can you do a quick test to make sure the shuffle write size is 
the expected size? For example, in logistic regression only the gradient should 
be serialized which is an array of `numFeatures` doubles. The expected shuffle 
write size is then roughly `numFeatures * 8 bytes` for each task. It would be 
nice to check before/after.
