Description

Validates End2End Distributed Scheduling flow which includes

1. the AM specifying OPPORTUNISTIC containers in its resource requests (YARN-2882, YARN-4335)
2. the Request intercepted by the AMRMProxyService running on the NM and handled by the LocalScheduler RequestInterceptor (YARN-2884, YARN-2885)
3. use of the DistributedSchedulingProtocol to talk to the DistributedSchedulingService running on the RM to obtain list of lightly loaded Nodes (YARN-2885, YARN-4412)
4. use of the OpportunisticContainerAllocator to create Container tokens which are returned to the AM (YARN-2885)
