Subject [jira] [Created] (MESOS-9284) mesos.proto comment falsely claims that non-persistent volumes are supported

Bruce Merry created MESOS-9284:
----------------------------------

             Summary: mesos.proto comment falsely claims that non-persistent volumes are supported
                 Key: MESOS-9284
                 URL: https://issues.apache.org/jira/browse/MESOS-9284
             Project: Mesos
          Issue Type: Documentation
          Components: documentation
    Affects Versions: 1.7.0, 1.5.2
            Reporter: Bruce Merry


According to mesos.proto,
{quote}// NOTE: If 'volume' is set but 'persistence' is not set, the
// volume will be automatically garbage collected after
// task/executor terminates. Currently, if 'persistence' is set,
// 'volume' must be set.
{quote}
However, when actually trying to set 'volume' but not 'persistence', one gets a TASK_ERROR
with the message "Task uses invalid resources: Invalid DiskInfo: Non-persistent volume not
supported".

I've run into this on 1.5.2, but I can see that validation code is still present on master
so I've tagged this bug for 1.7.0 as well. I will submit a patch to change the documentation
in mesos.proto.
