Subject Re: [DISCUSS] Merge yarn-native-services branch into trunk
Date Wed, 16 Aug 2017 17:29:10 GMT
Hi Jian,

Hadoop 3.0.0-beta1 is planned for mid-September. 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.

Best,
Andrew
