             Summary: Invalid resources sent to '/reserve' are silently dropped
                 Key: MESOS-5664
                 URL: https://issues.apache.org/jira/browse/MESOS-5664
             Project: Mesos
          Issue Type: Bug
    Affects Versions: 0.28.2
            Reporter: Greg Mann


If an invalid resource is passed to the master's {{/reserve}} endpoint, it will be silently dropped and not cause an error. This can lead, for example, to a {{/reserve}} request containing a single invalid resource receiving a 200 OK response, despite the fact that no resources were reserved as a result of the request.

This is due to the fact that the {{+=}} operator for {{Resources}} silently drops invalid resources, and this operator is used when parsing the resources in the HTTP request. This could be addressed by validating the resource objects one at a time as they are parsed.
