well. unfortunately these things are started in the ClusterClient
constructor, so we do have to call super, or refactor the client to only
instantiate those when needed.
> Create RESTful cluster endpoint
> -------------------------------
>
> Key: FLINK-7072
> URL: https://issues.apache.org/jira/browse/FLINK-7072
> Project: Flink
> Issue Type: Sub-task
> Components: Distributed Coordination
> Reporter: Till Rohrmann
> Assignee: Chesnay Schepler
> Labels: flip-6
> Fix For: 1.4.0
>
>
> 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.
