Hi,
Did you see hadoop-0.16.0/src/contrib/ec2/bin/start-hadoop script? It
already contains such part:
echo "Copying private key to slaves"
for slave in `cat slaves`; do
scp $SSH_OPTS $PRIVATE_KEY_PATH "[EMAIL PROTECTED]:/root/.ssh/id_rsa"
ssh $SSH_OPTS "[EMAIL PROTECTED]" "chmod 600 /root/.ssh/id_rsa"
sleep 1
done
Anyway, did you tried hadoop-ec2 script? It works well for task you
described.

Hi All,
I have been trying to configure Hadoop on EC2 for large number of clusters (
100 plus). It seems that I have to copy EC2 private key to all the machines in
the cluster so that they can have SSH connections.
For now it seems I have to run a script to copy the key file to each of the
EC2 instances. I wanted to know if there is a better way to accomplish this.
Thanks,
PA
