[jira] [Created] (KAFKA-8777) Trogdor - Add GET /coordinator/tasks/ids endpoint

Stanislav Kozlovski created KAFKA-8777:
------------------------------------------

             Summary: Trogdor - Add GET /coordinator/tasks/ids endpoint
                 Key: KAFKA-8777
                 URL: https://issues.apache.org/jira/browse/KAFKA-8777
             Project: Kafka
          Issue Type: Improvement
            Reporter: Stanislav Kozlovski


When scheduling a non-trivial Trogdor workoad (e.g 15 agents and 150 tasks), it is difficult to diagnose all the tasks that are running.

The output of `GET /coordinator/tasks` can get very large - 28.6MB in my case. This is mainly due to running a lot of ProduceBenchSpec tasks which are subscribed to a lot of topics.

I think we should have a simpler endpoint which exposes all the task IDs that are running. This can let us get the IDs to query specific tasks via `GET /coordinator/tasks?taskId=<id1>,<id2>` ot `GET /coordinator/tasks/<task_id>`
