I am using hadoop's in-built ec2-scripts to launch hadoop clusters in ec2. For lower instance-types ( upto m2.2xlarge ) the launch scripts work fine. But when I move to either m2.4xlarge or c1.xlarge instances, the same scripts seem to get stuck. For c1.xlarge it gives connection-time out and for m2.4xlarge it just didnt seem to proceed further after launching the master. Since I am using the exact same AMI ( because m2.2xlarge runs fine with 64 bit setup ) , I wasn't sure whether the problem is in AWS's ec2 or I need to do tweak something on my side.
Thanks, -Prasen
