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. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
