    I think you could also use the `ExecutorThreadFactory` for this purpose.

> In order to communicate with the cluster from the RESTful client, we have to implement
a RESTful cluster endpoint. The endpoint shall support the following operations:
> * List jobs (GET): Get list of all running jobs on the cluster
> * Submit job (POST): Submit a job to the cluster (only supported in session mode)
> * Get job status (GET): Get the status of an executed job (and maybe the JobExecutionResult)
> * Lookup job leader (GET): Gets the JM leader for the given job
> This endpoint will run in session mode alongside the dispatcher/session runner and forward
calls to this component which maintains a view on all currently executed jobs.
> In the per-job mode, the endpoint will return only the single running job and the address
of the JobManager alongside which it is running. Furthermore, it won't accept job submissions.
