> I had a config-group with 2 hosts which had YARN_CLIENTs and NodeManagers.
> When I changed configs in that config-group, it correctly showed on the
> service page the component-count and the hosts-count.
> However when you go to the host page and restart only the NodeManager, there
> is no warning for the YARN_CLIENT needing restart. However when I look at the
> API below, the YARN_CLIENT for the host is shown as stale.
