PXRuntime no down time support for Walmart

See this idea on ideas.ibm.com

We need a product enhancement to support no down time during the OpenShift maintenance. OpenShift maintenance typically requires node restart. If DataStage PXRuntime pods were running on those worker nodes, the jobs will fail.

If we have a control over where (which pods) the incoming jobs should be dispatched, we can avoid the pods on the worker that needs to be put in maintenance, and wait for the pods on that worker to complete all jobs. Then, we can shutdown the target worker nodes safely without having to aborting the jobs.

To accomplish this,

•Requires a new capability to mark the POD to not dispatch any more OSH tasks.

•The PODs with this flag continues running existing tasks but not new ones after being marked as “maintenance”.

•The jobs on those POD will finish the process and eventually the POD will drain out all OSH processes.

•Also need helper commands:

•get-pod-maintenance, set-pod-maintenance, unset-pod-maintenance, list-jobs-on-pod, etc

Please see the attached document for more details.
