Eric Yang commented on YARN-8734:
---------------------------------

[~gsaha] Local service would imply the current service itself in my 
imagination.  External service may imply service running out side of the 
current Hadoop cluster.  This was the reason that remote service was chosen 
during development.  However, I don't have strong preference to label it as 
remote service, or external service.

> When a service is deploying, there can be remote service dependency.  It 
> would be nice to describe ZooKeeper as a dependent service, and the service 
> has reached a stable state, then deploy HBase.
