Subject why are two Fetcher classes in Tez
Date Fri, 06 Jun 2014 22:20:56 GMT
one in in org.apache.tez.runtime.library.common.shuffle.impl
the other is in org.apache.tez.runtime.library.shuffle.common

Why don't we merge them together?

Looks like the second one is used in broadcastShuffleManager
but the first one is used in other shuffleManager.

There should be a way to merge them together, reuse some code,
 and avoid confusion.
