----------------------------------

[~sandyr] is this still relevant given more recent work on YARN data locality?

> In yarn-cluster mode, if the user passes preferred node location data to the SparkContext, the AM requests containers based on that data.
> In yarn-client mode, it would be good to do this as well.  This required some way of passing this data from the client process to the AM.
