Junping Du commented on MAPREDUCE-6146:
---------------------------------------

Hi [~vinodkv], I used to run normal MR application with this tar-ball. However, 
from a recently issue identified in hadoop-streaming, I think we could miss 
that jar in hadoop-tools. Will deliver an update patch to take care of this and 
do verification later. 
Let's cancel the patch first.

> Reduce tar ball size for MR over distributed cache

> The current tar ball built from "mvn package -Pdist -DskipTests -Dtar" is 
> over 160M in size. We need more smaller tar ball pieces for feature like MR 
> over distributed cache to support Rolling update of cluster.
