> I have tried to force reducers to execute on certain nodes. What I did is I changed for reduce tasks, the RMContainerRequestor#addResourceRequest(req.priority, ResourceRequest.ANY, req.capability) to RMContainerRequestor#addResourceRequest(req.priority, HOST_NAME, req.capability).
> However, this change lead to RM crashes when reducers needs to be assigned with the following exception:
> FATAL org.apache.hadoop.yarn.server.resourcemanager.ResourceManager: Error in handling event type NODE_UPDATE to the scheduler
