Carlo Curino commented on YARN-5412:
------------------------------------
[~giovanni.fumarola], per our offline discussion:
You can probably fix the tests issues by:
# add a {{capacity-scheduler.xml}} to test/resources,
# fix the {{yarn-default.xml}} (mistakenly setting rm.webaddress instead of
router.webaddress),
# add timeouts to the tests, so it timeouts locally and invokes shutdown,
avoiding other tests to fail due to binding issues (more local errors help)
Also completing a first pass on the review:
# {{TestRouterWebServices}} remove LOG.info that are redundant to asserts
# {{TestRouterWebServicesREST}} factor out code in setup to a
{{isWebAppRunning}} generic method (with a path in input)
# {{TestRouterWebServicesREST}} factor out all the invocations to something
like {{private List<T> performTest(Path, T.class)}}, the return list allows you
to add specific size checks outside where appropriate.

> As detailed in the proposal in the umbrella JIRA, we are introducing a new
> component that routes client request to appropriate ResourceManager(s). This
> JIRA tracks the creation of a proxy for ResourceManager REST API in the
> Router. This provides a placeholder for:
> 1) throttling mis-behaving clients (YARN-1546)
> 3) mask the access to multiple RMs (YARN-3659)
> We are planning to follow the interceptor pattern like we did in YARN-2884 to
> generalize the approach and have only dynamically coupling for Federation.
