Error on Teardown attempt: Framework is not connected via HTTP
We're getting the highlighted error message returned when attempting to
tear down a framework on our cluster:
june@cluster:~$ mesos frameworks
ID NAME HOST
ACTIVE TASKS CPU MEM DISK
0c540ad0-a050-4c20-82df-7bd14ce95f51-0090 pyspark-shell cluster True
4 115.0 450560.0 0.0
june@cluster:~$ curl -XPOST http://cluster:5050/api/v1/scheduler -d '{
"framework_id": { "value": "0c540ad0-a050-4c20-82df-7bd14ce95f51-0090" },
"type": "TEARDOWN"}' -H Content-Type:application/json
Framework is not connected via HTTP
We cannot get this framework to shut down. I'm not sure why we're getting
this type of error message, as the same POST command has worked against
other framework IDs in the past.
Your thoughts are much appreciated.
Thanks,

That's not the endpoint you want (that's for frameworks to use). You want
/teardown endpoint (that's for operators).

The `py-spark` framework looks to be driver based i.e. it uses the `MesosSchedulerDriver` underneath. You would need to use the `/teardown` endpoint that takes in the `frameworkId`as a query parameter for tearing it down. For more details, see: http://mesos.apache.org/documentation/latest/endpoints/master/teardown/ <http://mesos.apache.org/documentation/latest/endpoints/master/teardown/>
The `TEARDOWN` call to `/api/v1/scheduler` endpoint only works if your framework is using the new Scheduler API <http://mesos.apache.org/documentation/latest/scheduler-http-api/>. Hope this helps.
