Subject [jira] [Commented] (YARN-8200) Backport resource types/GPU features to branch-2
Date Tue, 01 May 2018 01:02:00 GMT

Konstantin Shvachko commented on YARN-8200:
-------------------------------------------

[~sunilg], thanks for the hints on the benchmarks.
Also I agree we should branch off of branch-2 rather than 2.9. Will re-branch.

> Currently we have a need for GPU scheduling on our YARN clusters to support deep learning
workloads. However, our main production clusters are running older versions of branch-2
(2.7 in our case). To prevent supporting too many very different hadoop versions across multiple
clusters, we would like to backport the resource types/resource profiles feature to branch-2,
as well as the GPU specific support.
>  
> We have done a trial backport of YARN-3926 and some miscellaneous patches in YARN-7069 based
on issues we uncovered, and the backport was fairly smooth. We also did a trial backport of
most of YARN-6223 (sans docker support).
>  
> Regarding the backports, perhaps we can do the development in a feature branch and then
merge to branch-2 when ready.
