[jira] [Created] (FLINK-9612) Add option for minimal artifacts being pulled in meseos

Addison Higham created FLINK-9612:
-------------------------------------

             Summary: Add option for minimal artifacts being pulled in meseos
                 Key: FLINK-9612
                 URL: https://issues.apache.org/jira/browse/FLINK-9612
             Project: Flink
          Issue Type: Improvement
          Components: Docker, Mesos
            Reporter: Addison Higham


NOTE: this assumes mesos, but this improvement could also be useful for future container deployments.

Currently, in mesos, the FlinkDistributionOverlay  copies the entire `conf`, `bin`, and `lib` folders from the running JobManager/ResourceManager. When using docker with a pre-installed flink distribution, this is relatively inefficient as it pulls jars that are already baked into the container image.

A new option that disables pulling most (if not all?) of the FlinkDistributionOverlay could allow for much faster and more scalable provisions of TaskManagers. As it currently stands, trying to run a few hundred TaskManagers is likely to result in poor performance in pulling all the artifacts from the MesosArtifactServer
