> Currently on the NM, we have the {{AMRMProxy}} framework to intercept the AM <->
RM communication and enforce policies. This is used both by YARN federation (YARN-2915) as
well as Distributed Scheduling (YARN-2877).
> This JIRA proposes to introduce a similar framework on the the RM side, so that pluggable
policies can be enforced on ApplicationMasterService centrally as well.
> This would be similar in spirit to a Java Servlet Filter Chain. Where the order of the
interceptors can declared externally.
> Once possible usecase would be:
> the {{OpportunisticContainerAllocatorAMService}} is implemented as a wrapper over the
{{ApplicationMasterService}}. It would probably be better to implement it as an Interceptor.
