mesos - 在 "cgroup" "/var/lib/docker/overlay2"上安装 "/sys/**"到 rootfs "no subsystem for mount"“在 minidcos 上部署 apache spark 时

Question

我正在尝试部署 apache spark在 minidcos使用 dcos 目录。

当我安装elastic、kafka和prometheus时，它们安装成功，如下图所示。

但是当我安装 spark 时它失败了，服务调试中显示的错误是“TASK_FAILED:容器以状态 125 退出”

日志中完整的错误跟踪是-

    WARNING: Your kernel does not support swap limit capabilities or the cgroup is not mounted. Memory limited without swap.

我该如何解决这个错误？

Answer 1

您使用的是哪个版本的 minidcos？

我相信这是一个在版本 2019.02.16.0 中修复的问题.

升级到最新版本，运行minidcos docker doctor，然后重试。
