Error on Teardown attempt: Framework is not connected via HTTP

[June Taylor]

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.
