`---jifa.elastic-worker-idle-threshold=30`, does this parameter control the worker's survival time?

[mark8s]

I want to make the worker pod survive longer, but it seems that when I use this args configuration, it has no use. Did I use it wrong?

The startup parameters of my complete jifa-master are:

      args:
            - --jifa.role=master
            - --jifa.scheduling-strategy=elastic
            - --jifa.storage-pvc-name=jifa-pvc
            - --jifa.storage-path=/jifa-storage
            - --jifa.service-account-name=jifa-service-account
            - --jifa.elastic-worker-image=eclipsejifa/jifa:latest
            - --jifa.elastic-worker-idle-threshold=30

Yes.

But in the current implementation, master won't pass this config to elastic workers.

You can try to modify the logic in org.eclipse.jifa.server.service.impl.K8SWorkerScheduler#scheduleAsync.

Another way is to build a new worker image with config updated.

I'll file a PR to fix the problem that master cannot control all configs of elastic workers.
