When running the Pumpkin framework for the Web Services and Cloud-based Systems course and trying to deploy different seeds on different VMs, the different seeds can not really find each other. We tried to run the 'tweetinject' and 'filter' seed on one VM and the 'collector' seed on another VM. The first VM did manage to find a 'collector' seed, but on a different IP address (maybe an IP address of another group).
The image below shows the output from running ./run_pumpkin.sh on the first VM
The image below shows the output from running ./run_pumpkin.sh on the second VM
After this, there is no more output, the program just keeps running
