      Description

      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 + Standalone. For MPI, what we need is password-less SSH access among workers. We might also consider other distributed frameworks, like distributed tensorflow, H2O, etc.
