Hello all, first time user, trying to get more acquainted wtih Hadoop/mapreduce
I'm trying to get the demo cluster on AWS, and I when I hit create, I get this error:
Template validation error: Parameter KeyName failed to satisfy constraint: can contain only ASCII characters.
I am not sure that is an issue wtih the supplied template or the key value pair I entered, or dikdn't enter (I tried empty or just a simple test/test)
Any help would be graciously recieved, I need to learn this quickly.
If you're also getting an error about the key name, have you ensured you're entering the name of a valid keypair on EC2?
