First of all, if you can get all machines to have the same user, that would greatly simplify things.
If, for whatever reason, you absolutely can't get the same user on all machines, then you could do either of the following: 1) Change the *-all.sh scripts to read from a slaves file that has two fields: a host and a user 2) Move away from the *-all.sh scripts and do your own SSHing. The *-all.sh scripts just SSH to other machines and run hadoop-daemon.sh, which actually does the starting and stopping. You could write your own little script (bash, Python, whatever) that read from your own slaves files and did the SSHing and hadoop-daemon.sh calling. Again, ideally you'll have one user.
