> Key: SPARK-24724
> URL: https://issues.apache.org/jira/browse/SPARK-24724
> Project: Spark
> Issue Type: Story
> Components: Kubernetes, ML, Spark Core
> Affects Versions: 3.0.0
> Reporter: Xiangrui Meng
> Assignee: Yinan Li
> Priority: Major
>
> In barrier mode, to run hybrid distributed DL training jobs, we need to
> provide users sufficient info and access so they can set up a hybrid
> distributed training job, e.g., using MPI.
> This ticket limits the scope of discussion to Spark + Kubernetes. There were
> some past and on-going attempts from the Kubenetes community. So we should
> find someone with good knowledge to lead the discussion here.
