Sangjin Lee commented on YARN-3033:
-----------------------------------
[~djp], I think it'd be good to support *both* options.
I do see some may want to run it as an aux service for simplicity of
deployments (one fewer daemons to start), especially in a small setup. However,
we do need to address the web app issue at YARN-3087 to avoid the undesirable
module dependency.
A standalone is probably safer as it would affect the node manager less. We
still need to poke this daemon for the AM lifecycle (thus the service part).
