> 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.
