Hi Gianmarco and Nicolas, Yes, it does. Can you tell me which version of SAMOA and Storm you have running in your cluster? I will try to set up a new cluster from scratch to see if I manage to get it to work. Also, can you tell me if your clusters’ nodes are VMs? And you many RAM each has? Finally, do you have any changes to your garbage collection on storm, or everything is as default?
Nicolas, I honestly don’t recall where I saw this example using com.yahoo classes. Should I use others instead?
