SLIDER-183 enabled running long running applications (services) on YARN. Apache Ambari Slider View provides us a way to deploy and manage long running services on YARN.
However, the Slider View provides a limited functionality and does not provide a first class support for YARN hosted services similar to traditional services deployed directly on the hosts by Ambari.
Besides while YARN-896 got the ball rolling for supporting services on YARN, the YARN team is working on major improvements and a first class support for YARN hosted services (YARN-4692).
This initiative is for providing a first class support for YARN-hosted services and leverage all the YARN improvements planned and documented in YARN-4692.
