Navina Ramesh commented on SAMZA-619:
-------------------------------------
[~closeuris]
ResourceRequest is an internal yarn data structure that is used on the Yarn
Protocol (org.apache.hadoop.yarn.api.records.ResourceRequest). It is not part
of the yarn client library. Hence, I don't think it is a good idea to directly
use an internal class definition.

> 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.
