> In order to enable host-affinity in YARN, the Samza App Master must include the node list in the resource request. 
> The node list can be obtained from the Job Coordinator that provides the container-to-host mapping (SAMZA-618)
> YARN must also be configured to use FairScheduler with continuous scheduling.
