想搭建一个环境使用GPU来跑tensorflow任务，添加了yarn 使用 GPU 的配置之后，修改了hadoop的配置
在 container-executor.cfg 中添加配置：
[docker]
docker.allowed.volume-drivers=/usr/bin/nvidia-docker
docker.allowed.devices=/dev/nvidiactl,/dev/nvidia-uvm,/dev/nvidia-uvm-tools,/dev/nvidia1,/dev/nvidia0
docker.allowed.ro-mounts=nvidia_driver_375.26
[gpu]
module.enabled=true
[cgroups]
# /sys/fs/cgroup是cgroup的mount路径
# /hadoop-yarn是yarn在cgroup路径下默认创建的path
root=/sys/fs/cgroup
yarn-hierarchy=/hadoop-yarn
然后启动nodemanager失败，日志如下：

另外，在本地也做了docker的镜像来验证环境，在本地的docker到时没有什么问题，可以正常启动服务，将镜像上传到服务器测试的时候，遇到的也还是同一个问题，也不知道是不是cgroup挂载的问题，有没有大神解答一二，感谢感谢。
