    [ https://issues.apache.org/jira/browse/YARN-3988?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14644863#comment-14644863

Allen Wittenauer commented on YARN-3988:
----------------------------------------

It's a bit of a security hole to let users dictate docker run params....

>             Project: Hadoop YARN
>          Issue Type: Sub-task

> In current DockerContainerExecutor, the "docker run" command has fixed parameters:
> String commandStr = commands.append(dockerExecutor)
>       .append(" ")
>       .append("run")
>       .append(" ")
>       .append("--rm --net=host")
>       .append(" ")
>       .append(" --name " + containerIdStr)
>       .append(localDirMount)
>       .append(logDirMount)
>       .append(containerWorkDirMount)
>       .append(" ")
>       .append(containerImageName)
>       .toString();
> For example, it is not flexible if users want to start a docker container with attaching
extra volume(s) and other "docker run" parameters.
