HINT: Password-less here SSH is not just because Doug wanted so. :)
/bin/bash with SSH/scp are your very opensource friends, e.g.:

for hostname in `cat $HADOOP/slaves`;
   echo "Doing stuff on $hostname";
   scp /local/file.txt $hostname:/path/on/remote/host/;
   ssh $hostname cat /path/on/remote/host/file.txt;

P.S. Make sure "slaves" does not contains local host's IP. :-)
