The start and stop scripts have directory layout assumptions. The
alternative is to use hadoop-daemon.sh to start/stop manually each service on
each node. To work around different users, you might need to modify the
members list of the supergroup. But I don't remember if that is necessary or
not.
It should be noted that using different users and different directory
layouts is not recommended and you will likely end up being very very
frustrated.
