在minidcos上部署apache spark时，将“cgroup”挂载到rootfs“/ var / lib / docker / overlay2”at“/ sys / **”“no subsystem for mount”“

Question

我正在尝试使用dcos目录在apache spark上部署minidcos。

当我安装弹性，卡夫卡和普罗米修斯时，它已成功安装，如下图所示。

但是当我安装spark时它失败并且服务调试中显示的错误是“TASK_FAILED：Container退出状态为125”

日志中的完整错误跟踪是 -

我该如何解决这个错误？

Answer 1

你使用的是哪个版本的minidcos？

我相信这是一个在2019.02.16.0版本中修复的问题。

升级到最新版本，运行minidcos docker doctor然后再试一次。

Answer 2

找到它所在的节点的docker容器：minidcos docker inspect 输入此节点：docker exec -it dcos-e2e-default-6af12-agent-1 bash（替换您找到的容器名称） 列出所有容器docker ps -a 显示失败的容器docker logs mesos-a500e80d-d694-4fb5-8baa-0b238f472f1f的日志
