Thank you, [~gphillips] for the patch. I think we need to check for single &, 
|, |& and ; as well in MULTI_COMMAND_REGEX.

> I set the sandbox to enforcing mode. Unfortunately I was able to break out of

>         cmd = "$JAVA_HOME/bin/java %s -Xmx825955249 
> org.apache.hadoop.yarn.applications.helloworld.HelloWorld `touch 
> ../../helloworld`" + \

> $ ls .../nm-local-dir/usercache/root/appcache/
> helloworld
> {code}
> Also, if I am not using sandboxes, could we create the nm-sandbox-policies 
> directory (empty) lazily?
