> https://github.com/apache/hadoop/blob/trunk/hadoop-mapreduce-project/hadoop-mapreduce-client/hadoop-mapreduce-client-common/src/main/java/org/apache/hadoop/mapreduce/v2/util/LocalResourceBuilder.java
> Add a new parameter to {{LocalResourceBuilder}} that allows the list of
> resources to be shuffled randomly. This will allow the Localizer to spread
> the load of requests so that not all of the NodeManagers are requesting to
> localize the same files, in the same order, from the same DataNodes,
