Hey Andro, I believe the reason you are seeing this error is due to ports being blocked by iptables. You need to have port 30000 open for the master on all machines in your cluster. You also need to open ports 30001 up to the number of workers you will be running. So if you are running 10 workers then add the following to /etc/sysconfig/iptables -A INPUT -p tcp -m state --state NEW -m tcp --dport 30000:30010 -j ACCEPT Then restart iptables with: sudo service iptables restart I'm new to Giraph too so anyone please correct me if I'm wrong. Regards, Simon
