[jira] [Created] (YARN-6355) Interceptor framework for the YARN
ApplicationMasterService
Arun Suresh created YARN-6355:
---------------------------------
Summary: Interceptor framework for the YARN ApplicationMasterService
Key: YARN-6355
URL: https://issues.apache.org/jira/browse/YARN-6355
Project: Hadoop YARN
Issue Type: Improvement
Reporter: Arun Suresh
Assignee: Arun Suresh
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.
