Question

从documentation开始，当节点进入mesos节点进入维护模式时，它会向所有框架发送反向提议。我对此的解释是，像Marathon这样的框架应该接收这些反向提议，并努力将任务移出计划维护的节点。

我使用API计划维护60秒：

curl -X POST leader.mesos:5050/maintenance/schedule \
  --data '{"windows": [{"machine_ids":[{"hostname": "host43.local"}], "unavailability": {"start": {"nanoseconds": '$(($(date +%s) + 60))'000000000}, "duration": {"nanoseconds": 3600000000000}}}]}'

然后，我查询维护状态并确认它正在耗尽：

$ curl leader.mesos:5050/maintenance/status | jq .
{
  "draining_machines": [
    {
      "id": {
        "hostname": "host43.local"
      }
    }
  ]
}

最后，一旦窗口接近，我就把它放下：

curl -X POST leader.mesos:5050/machine/down --data '[{"hostname": "host43.local"}]'

我确认它生效了：

$ curl leader.mesos:5050/maintenance/status | jq .
{
  "down_machines": [
    {
      "hostname": "hsot43.local"
    }
  ]
}

然后，我检查马拉松（通过用户界面），并看到仍有host43.local上的任务正在运行。

我在马拉松日志中看到此错误消息，我想知道它是否相关：

如果我用马拉松手动杀死任务，它们似乎不会在正在进行维护的节点上分配。似乎行为应该是节点被自动迁移出去，我不知道我做错了什么，或者我是否遇到过错误，或者我是否误解了文档和预期的行为。

运行Marathon 1.1.1和Mesos 0.28

收到DC / OS闲聊聊天室的回复并在此处发布，以造福他人。 Marathon尚不支持Mesos维护原语。

以下JIRA票证跟踪该功能：

不从mesos节点迁移的Marathon任务进入排水模式
