[jira] [Commented] (SPARK-24724) Discuss necessary info and access in barrier mode + Kubernetes
[ https://issues.apache.org/jira/browse/SPARK-24724?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel=16630912#comment-16630912 ] Stavros Kontopoulos commented on SPARK-24724: - AFAIK in standalone mode passwordless communication is needed between workers or in general between master-workers. Right now the design proposal uses netty rpc for task coordination for the barriers via the default rpc Env (env.rpcEnv.setupEndpoint call). For that part I dont see any issue, but when mpi tasks are run they may need extra net configuration? > Discuss necessary info and access in barrier mode + Kubernetes > -- > > 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.

What pieces of info and what kind of access we need to provide? I saw some comments on thesimilar Jira for Yarn and particularly the one quoted below: "The main problem is how to provide necessary information for barrier tasks to start MPI job in a password-less manner". Is the main problem the same for Kubernetes? > Discuss necessary info and access in barrier mode + Kubernetes > -- > > 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.
