在 minidcos 上部署 apache spark 时，将 "cgroup" 安装到位于“/sys/**”"no subsystem for mount"”的根文件系统“/var/lib/docker/overlay2”

Question

我正在尝试使用 dcos 目录部署 apache spark on minidcos。

安装elastic、kafka、prometheus时安装成功，如下图

但是我安装spark的时候失败了，服务debug中显示的错误是"TASK_FAILED : Container exited with status 125"

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.
    container_linux.go:247: starting container process caused "process_linux.go:359:

有关我系统中安装的组件的其他详细信息是 --

我该如何解决这个错误？

Answer 1

找到它在其中启动的节点的 docker 容器： minidcos docker inspect
输入这个节点：docker exec -it dcos-e2e-default-6af12-agent-1 bash（替换你找到的容器名）
列出所有容器 docker ps -a
显示失败容器的日志 docker logs mesos-a500e80d-d694-4fb5-8baa-0b238f472f1f

Answer 2

您使用的 minidcos 是哪个版本？

我认为这是一个已在版本 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。
