# How to download the user jars I agree with Gyula that it will be a burden if we bundle the flink filesystem dependencies in the operator image. Maybe we could have a *ArtifactFetcher* interface in the flink-kubernetes-operator. By default, we provide the local and http implementation, which means we could get the user jars from local files or HTTP URLs. Flink filesystem support could be done as a follow-up based on the feedback.
If the user wants to use the local implementation, they need to mount a PV(aka persist volume) to the operator first and then put their jars into the PV. # How to talk to session JobManager to submit the job After more consideration, I also prefer the second approach, via REST API /jars/:jarid/run. If we have strong requirements to support dependencies jars and artifacts, we could try to support this in the upstream project.
