Description

When I launched a task with an non-existent user in its commandInfo via mesos-execute, see the JSON below for the task info (the user xxx does not exist in the agent host):

{
  "name": "test",
  "task_id": {"value" : "test"},
  "agent_id": {"value" : ""},
  "resources": [
    {"name": "cpus", "type": "SCALAR", "scalar": {"value": 0.1}},
    {"name": "mem", "type": "SCALAR", "scalar": {"value": 32}}
  ],
  "command": {
    "value": "sleep 1000",
    "user": "xxx"
  },
  "container": {
    "type": "MESOS",
    "mesos": {
      "image": {
        "type": "DOCKER",
        "docker": {
          "name": "library/busybox"
        }
      }
    }
  }
}

I found agent crashed immediately:
