YARN servers and ports
What service addresses and ports does a YARN ApplicationMaster need to know about?
Thanks,
John

If you're asking in terms of discovering where to communicate at, then
basically just the RM scheduler address and port
(yarn.resourcemanager.scheduler.address).
The NodeManager addresses and ports are carried back from the RM to
the requesting AM as part of container requests and needn't be in the
config (and hence the NMs can be using dynamic ports if they wanted
to).
