> Revisit RMWebServiceProtocol implementations
> --------------------------------------------
>
> Key: YARN-8046
> URL: https://issues.apache.org/jira/browse/YARN-8046
> Project: Hadoop YARN
> Issue Type: Improvement
> Reporter: Wangda Tan
> Priority: Critical
>
> I recently found that new changes of RMWebServiceProtocol make adding any new
> REST API is pretty hard. There're at least 6 classes need to be implemented:
> 1. {{MockRESTRequestInterceptor}}
> 2. {{FederationInterceptorREST}}
> 3. {{DefaultRequestInterceptorREST}}
> 4. {{PassThroughRESTRequestInterceptor}
> 5. {{RouterWebServices}}
> 6. {{RMWebServices}}
> Different classes implementations have different styles, simple copy-paste is
> not enough. For example.
> {{DefaultRequestInterceptorREST}} uses
> {{RouterWebServiceUtil.genericForward}} to pass all parameters, which needs
> to understand how each REST API works, reconstruct an URL which can easily
> cause issues.
> I think we should revisit these APIs and make sure new API can be easier
> added to REST interface like before.
