I don't think you can tell start-all.sh to log in as a different user on certain nodes. Why not just create the same user on the fourth node?
An alternative would be to start the fourth node manually via hadoop-daemon.sh script. Here's an example: bin/hadoop-daemon.sh start datanode bin/hadoop-daemon.sh start tasktracker Those commands should be run on the fourth node. This allows you to bypass the SSH step that start-all.sh does. Alex On Thu, Apr 16, 2009 at 11:24 PM, Puri, Aseem <[email protected]>wrote: > Hi > > I am running Hadoop Cluster on windows.
