Re: Differences between HistoryServer and Yarn TimeLine server?
1 and 4:
We have thought about that in addition to service application specific
data, the timeline server should accept the web UI plugin from the
application, install it and render the data on the web page according the
application's design, but still need to figure out the plan. Before that,
the application needs to take care of the data rendering itself, or make
use of third-party monitoring service, such as Ambari, which AFAIK, has
integration with the timeline server in the recent release (Tez is
leveraging it). And yes, it's always welcome if somebody want to contribute.

REST APIs are available for accessing both the generic data and framework
specific data. For the API specification, you can temporally look at the
patch in YARN-1876.

In terms of services, they're almost there. The next step would be about
the security, scalability and integration stuff.
