spec
MPIJobSpec

Specification of the desired state of the MPIJob.

`mainContainer` string	(Optional) Specifies name of the main container which executes the MPI code.
`runPolicy` common/v1.RunPolicy	(Optional) Encapsulates various runtime policies of the distributed training job, for example how to clean up resources and how long the job can stay active.
`mpiReplicaSpecs` map[github.com/kubeflow/mpi-operator/pkg/apis/kubeflow/v1alpha2.MPIReplicaType]github.com/kubeflow/tf-operator/pkg/apis/common/v1.ReplicaSpec*	A map of MPIReplicaType (type) to ReplicaSpec (value). Specifies the MPI cluster configuration. For example, { “Launcher”: MPIReplicaSpec, “Worker”: MPIReplicaSpec, }
