Hi Steve,
Thanks!
But I'm confused when I looked at the code.
What is RegistryRestResources? Looks like you can register your own REST
API through this? Is there an example of doing so?
The limit of YARN web server you were talking about is on the WebApp class?
So you can actually start an fully functional embedded jetty server in the
AM and set the tracking url to this {amhost:port}?
Best,
Siyuan
