> Spark EC2 scripts fail when trying to log in to EC2 instances
> -------------------------------------------------------------
>
> Key: SPARK-2396
> URL: https://issues.apache.org/jira/browse/SPARK-2396
> Project: Spark
> Issue Type: Bug
> Components: EC2
> Affects Versions: 1.0.0
> Environment: Windows 8, Cygwin and command prompt, Python 2.7
> Reporter: Stephen M. Hopper
> Labels: aws, ec2, ssh
>
> I cannot seem to successfully start up a Spark EC2 cluster using the
> spark-ec2 script.
> I'm using variations on the following command:
> ./spark-ec2 --instance-type=m1.small --region=us-west-1 --spot-price=0.05
> --spark-version=1.0.0 -k my-key-name -i my-key-name.pem -s 1 launch
> spark-test-cluster
> The script always allocates the EC2 instances without much trouble, but can
> never seem to complete the SSH step to install Spark on the cluster. It
> always complains about my SSH key. If I try to log in with my ssh key doing
> something like this:
> ssh -i my-key-name.pem root@<insert ip of my instance here>
> it fails. However, if I log in to the AWS console, click on my instance and
> select "connect", it displays the instructions for SSHing into my instance
> (which are no different from the ssh command from above). So, if I rerun the
> SSH command from above, I'm able to log in.
> Next, if I try to rerun the spark-ec2 command from above (replacing "launch"
> with "start"), the script logs in and starts installing Spark. However, it
> eventually errors out with the following output:
> Cloning into 'spark-ec2'...

> So, in short, am I missing something or is this a bug? Any help would be

> Other notes:
> -I've tried both us-west-1 and us-east-1 regions.
> -I've tried several different instance types.
> -I've tried playing with the permissions on the ssh key (600, 400, etc.), but
> to no avail
