[jira] [Created] (SPARK-24726) Discuss necessary info and access in
barrier mode + Standalone
Xiangrui Meng created SPARK-24726:
-------------------------------------
Summary: Discuss necessary info and access in barrier mode + Standalone
Key: SPARK-24726
URL: https://issues.apache.org/jira/browse/SPARK-24726
Project: Spark
Issue Type: Story
Components: ML, Spark Core
Affects Versions: 3.0.0
Reporter: Xiangrui Meng
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 + YARN. There were some past attempts from the Hadoop community. So we should find someone with good knowledge to lead the discussion here.
