Eric Yang commented on YARN-8734:
---------------------------------
[~gsaha], I see what you mean. It will be corrected in the next patch.
[~billie.rinaldi] [~gsaha], there appears to be a serialization problem when
service level object use the same keyword as the component level. When I
changed to use keyword "dependencies", Jersey fails with a generic error
message:

Do we want to choose another keyword other than "dependencies"? I also
verified the ServiceMonitor is registered in serviceInit, it happens prior to
start() method. Therefore, app master does not get terminated by
yarn.am.liveness-monitor.expiry-interval-ms setting, when dependencies are not
satisfied.

> 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.
