Emmanuel: You're correct in that ssh is hard coded in the start-*.sh scripts. You can either use Cloudera's distribution (which comes with init scripts that run on each node like other services) or you can roll your own start up scripts and invoke the underlying hadoop-daemon.sh scripts on each node over whatever communication channel you'd like. You may have to do a little environment setup first if you choose to go this route. Take a look at the source of start-*.sh; they're pretty simple. Hope this helps. -- Eric Sammer e...@lifeless.net http://esammer.blogspot.com
