> Existing YARN native service overwrites 
> YARN_CONTAINER_RUNTIME_DOCKER_LOCAL_RESOURCE_MOUNTS regardless if user 
> specified this in service spec or not. It is important to allow user to mount 
> local folders like /etc/passwd, etc.
> Following logic overwrites the 
> YARN_CONTAINER_RUNTIME_DOCKER_LOCAL_RESOURCE_MOUNTS environment:
> {code:java}
> StringBuilder sb = new StringBuilder();
> for (Entry<String,String> mount : mountPaths.entrySet()) {
>   if (sb.length() > 0) {
>     sb.append(",");
>   }
>   sb.append(mount.getKey());
>   sb.append(":");
>   sb.append(mount.getValue());
> }
> env.put("YARN_CONTAINER_RUNTIME_DOCKER_LOCAL_RESOURCE_MOUNTS", 
> sb.toString());{code}
> Inside AbstractLauncher.java
