ssh connection refused
I'm trying to launch Spark with this command on AWS: *./spark-ec2 -k keypair_name -i keypair.pem -s 5 -t c1.xlarge -r us-west-2 --hadoop-major-version=2.4.0 launch spark_cluster* This script is erroring out with this message: *ssh: connect to host hostname port 22: Connection refused Error executing remote command, retrying after 30 seconds*: Command '['ssh', '-o', 'StrictHostKeyChecking=no', '-i', 'keypair.pem', '-t', '-t', u'root@hostname', \n [ -f ~/.ssh/id_rsa ] ||\n(ssh-keygen -q -t rsa -N '' -f ~/.ssh/id_rsa \n cat ~/.ssh/id_rsa.pub ~/.ssh/authorized_keys)\n]' returned non-zero exit status 255 Strange this is, I can manually ssh to master node as root using this command: *ssh root@hostname -i keypair.pem* Does anyone know what is going on here?

Re: ssh connection refused
This may occurred while the ec2 instance are not ready and ssh port not open yet. Please give larger time by specify -w 300. Default should be 120 Thanks, Tracy Sent from my iPhone On 2014年7月29日, at 上午8:17, sparking research...@gmail.com wrote: I'm trying to launch Spark with this command on AWS: *./spark-ec2 -k keypair_name -i keypair.pem -s 5 -t c1.xlarge -r us-west-2 --hadoop-major-version=2.4.0 launch spark_cluster* This script is erroring out with this message: *ssh: connect to host hostname port 22: Connection refused Error executing remote command, retrying after 30 seconds*: Command '['ssh', '-o', 'StrictHostKeyChecking=no', '-i', 'keypair.pem', '-t', '-t', u'root@hostname', \n [ -f ~/.ssh/id_rsa ] ||\n(ssh-keygen -q -t rsa -N '' -f ~/.ssh/id_rsa \n cat ~/.ssh/id_rsa.pub ~/.ssh/authorized_keys)\n]' returned non-zero exit status 255 Strange this is, I can manually ssh to master node as root using this command: *ssh root@hostname -i keypair.pem* Does anyone know what is going on here?

0.9 wont start cluster on ec2, SSH connection refused?
I run the follwoing command and it correctly starts one head and one master but then it fails because it can't log onto the head with the ssh key. The wierd thing is that I can log onto the head with that same public key.

Re: 0.9 wont start cluster on ec2, SSH connection refused?
No not anymore but it was at the time. Thanks but I also just found a thread from two days ago discussing the root and es2-user workaround. For now I'll just go back to using the AMI provided.
