Hadoop/Thread Docker容器执行器失败，原因是；无效的docker rw mount“；

我正在尝试执行Hadoop/Thread（版本：2.9.1）Docker容器执行器的简单示例：

vars="YARN_CONTAINER_RUNTIME_TYPE=docker,YARN_CONTAINER_RUNTIME_DOCKER_IMAGE=hadoop-docker"
hadoop jar hadoop-examples.jar pi -Dyarn.app.mapreduce.am.env=$vars -Dmapreduce.map.env=$vars -Dmapreduce.reduce.env=$vars 10 100

不幸的是，作业失败，出现以下异常：

Failing this attempt.Diagnostics: [2018-09-08 22:23:54.288]Exception from container-launch.
Container id: container_1536441225683_0004_02_000001
Exit code: 29
Exception message: Invalid docker rw mount '/tmp/hadoop-hadoop/nm-local-dir/usercache/hadoop/appcache/application_1536441225683_0004/:/tmp/hadoop-hadoop/nm-local-dir/usercache/hadoop/appcache/application_1536441225683_0004/', realpath=/tmp/hadoop-hadoop/nm-local-dir/usercache/hadoop/appcache/application_1536441225683_0004/
Error constructing docker command, docker error code=14, error message='Invalid docker read-write mount'

任何人都知道如何解决无效的docker读写挂载？

通过将此目录添加到etc/hadoop/container executor.cfg中的属性docker.allowed.rw mounts来解决。如果您收到多个目录的错误消息，则需要添加逗号分隔的目录

就我而言：

docker.allowed.rw-mounts=/usr/local/hadoop/,/var/hadoop/yarn/local-dir,/var/hadoop/yarn/log-dir,/tmp/hadoop-hadoop/
