---------------------------------------
[~dbtsai] Apple Siri is a major user of Spark + Mesos. Do you know anyone (or yourself) who might be the best person to lead here?
> Discuss necessary info and access in barrier mode + Mesos
> ---------------------------------------------------------
>
> Key: SPARK-24725
> URL: https://issues.apache.org/jira/browse/SPARK-24725
> Project: Spark
> Issue Type: Story
> Components: ML, Spark Core
> Affects Versions: 3.0.0
> Reporter: Xiangrui Meng
> 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 + Mesos. I'm not aware of MPI support in Mesos. So we should find someone with good knowledge to lead the discussion here.
