Hi, I am following a setup guide here: http://wiki.apache.org/hadoop/AmazonEC2 but runs into problems when I tried to launch a cluster. An error message said "hadoop-0.21.0/common/src/contrib/ec2/bin/launch-hadoop-master: line 40: ec2-describe-instances: command not found" I am not even sure if I edited the hadoop-ec2-env.sh correctly. Is there any newer tutorial for setting this up?
Thanks!
