      Description

      mesos-execute documents that a task can be defined via JSON as

      {
        "name": "Name of the task",
        "task_id": {"value" : "Id of the task"},
        "agent_id": {"value" : ""},
        "resources": [
          {
            "name": "cpus",
            "type": "SCALAR",
            "scalar": {
              "value": 0.1
            },
            "role": "*"
          },
          {
            "name": "mem",
            "type": "SCALAR",
            "scalar": {
              "value": 32
            },
            "role": "*"
          }
        ],
        "command": {
          "value": "sleep 1000"
        }
      }
      

      If one actually uses that example task definition one gets

      % ./build/src/mesos-execute --master=127.0.0.1:5050 --task=task.json

      Removing the resource role field allows the task to execute.
