Thanks Andrew for the comments. Answers below: - There are no new APIs added in YARN/Hadoop core. In fact, all the new code are running outside of existing system and they are optional and require users to explicitly opt in. The new system’s own rest API is not stable and will be evolving. - We have been running/testing a version of the entire system internally for quite a while. - I’d like to see this in hadoop3-beta1. Of course, we’ll take responsibility of moving fast and not block the potential timeline.

If the plan is to merge in hopefully the next two weeks, that's very, very close to the goal release date. We've already got a pile of blockers and criticals to resolve before then. Could you comment on testing and API stability for this branch? YARN Federation was run at high scale and did not add new APIs, which provided a lot of confidence in the merge. I'll also raise the option of cutting branch-3 or branch-3.0 for the 3.0.0 efforts, and targeting this for 3.1.0.

There are a few issues left under YARN-5079 that are being actively worked upon. As soon as they are resolved, we plan on start a vote hopefully in next 2 weeks. The goal is to get this in for hadoop3 beta. The major work in this branch include below umbrella jiras: - YARN-5079. A native YARN framework (ApplicationMaster) to migrate and orchestrate existing services to YARN either docker or non-docker based. - YARN-4793. A Rest API server for user to deploy a service via a simple JSON spec - YARN-4757. Extending today's service registry with a simple DNS service to enable users to discover services deployed on YARN - YARN-6419. UI support for native-services on the new YARN UI All these new services are optional and have to be explicitly enabled. Special thanks to a team of folks who worked hard towards this: Billie Rinaldi, Gour Saha, Vinod Kumar Vavilapalli, Jonathan Maron, Rohith Sharma K S, Sunil G, Akhil PB. This effort could not be possible without their ideas and hard work. Please share your thoughts. Thanks.
