-------------------------------

             Summary: YARN should expose a ENV used to map a custom device into docker container
                 Key: YARN-10867
                 URL: https://issues.apache.org/jira/browse/YARN-10867
             Project: Hadoop YARN
          Issue Type: Improvement
            Reporter: Chi Heng


In some scenarios, like mounting a FUSE in docker,user needs to map a custom device (eg. /dev/fuse)
into docker container.I notice that an adddevice method is defined in [ hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-nodemanager/src/main/java/org/apache/hadoop/yarn/server/nodemanager/containermanager/linux/runtime/docker/DockerRunCommand.java
|http://gitlab.qiyi.domain/bigdata/hadoop/blob/branch-3.2.2/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-nodemanager/src/main/java/org/apache/hadoop/yarn/server/nodemanager/containermanager/linux/runtime/docker/DockerRunCommand.java]
,I suppose that an ENV or config property should to be exposed to user to call this method
