Anand Mazumdar created MESOS-6245:
-------------------------------------

             Summary: Schedulers performing explicit acknowledgements cannot acknowledge updates
from HTTP based executors.
                 Key: MESOS-6245
                 URL: https://issues.apache.org/jira/browse/MESOS-6245
             Project: Mesos
          Issue Type: Bug
            Reporter: Anand Mazumdar
            Assignee: Anand Mazumdar
             Fix For: 1.1.0, 1.0.2


It seems that the driver has an old check relying on the `PID`. The `PID` is always `UPID()`
for HTTP based executors. If a scheduler is using explicit acknowledgements, it won't ever
be able to acknowledge the update since the driver would clean up the {{uuid}} field!

Note that all our tests use implicit acknowledgements and we never got around to catching
this issue till Marathon started using the HTTP based executors.
