Hi @k82cn. Thanks for your PR.

I'm waiting for a kubeflow member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

Add api firstly, will add implementation later.

Could we support advanced use cases? For example, we want to run PS in different machines and place workers around PS.

You also discussed about adding queue name. Is it planned?

[k82cn]

yes, queue is a key feature in the pipeline. I will add integration when it is stable, e.g. QueueName.

Sorry for post update: there's a "feature" in upstream, named SchedulingPolicy, which is used to define whether a scheduler feature can be enabled, e.g. toleration. Do we need to have another term for that, e.g. SchedulingSpec?

@k82cn Thanks for the information, Kubeflow requires k8s 1.8, does this feature exist in 1.8?

nop, but this may make other contributor confuse.

BTW, I think it should be client-go 1.8, k8s 1.11 :)
