I've never dealt with a large cluster, though I'd imagine it is managed the same way as small clusters:
-Use hostnames or ips, whichever is more convenient for you -All the slaves need to go into the slave file -You can update software by using bin/hadoop-daemons.sh. Something like: #bin/hadoop-daemons.sh "rsync (mastersrcpath) (localdestpath)" I created a wiki page that currently contains one tip for managing large clusters. Could others add to this wiki page? <http://wiki.apache.org/hadoop/LargeClusterTips> Thanks. Hope this helps!
