Hi,
if you say you correctly setted your access key id and secret access key then probably it's a problem related to the key.pem file. Try generate a new one, and be sure to be the only one with the right to read it or it wont work.

Hi,

I am trying to launch an EC2 cluster from spark using the following command:

./spark-ec2 -k HackerPair -i [path]/HackerPair.pem -s 2 launch HackerCluster

I set my access key id and secret access key. I have been getting an error in the 
"setting up security groups..." phase:

Invalid value 'null' for protocol. VPC security groups must specify protocols 
explicitly.

My project partner gets one step further and then gets the error

The key pair 'JamesAndSamTest' does not exist.

Any thoughts as to how we could fix these problems? Thanks a lot!
Sam
