在 YARN 上实现了容器的那一套使得资源可以被抢占

仔细阅读了一下，并不是容器的一套使得资源可以被抢占，而是基于容器实现了 save 和 resume 的自己的一套方式，不被应用感知又很厉害，有点像 CRIU，我觉得这才是这篇文章最需要讲清楚的地方但是他没怎么讲。我很好奇这是怎么实现的。文章在 3.2 稍微讲了讲，看不懂。

有了这一层实现，那我觉得随随便便写一写下面的就好了。因为有了文章中的 save resume ，肯定比之前的 kill-based 抢占要好，这根本不用说。

可能是作者开源的实现，找了半天没找到 SR 的代码。。按理是在 DockerMonitor 里，但是作者在 issue 里说 PyDockerMonitor 是第一版，现在没用了，搞不懂搞不懂
