Using Eclipe export will package "storm-core.jar" and it's dependencies into you user jar. "storm-core.jar" contains the duplicate default.yaml class. You should not include "storm-core.jar" and its dependencies after all.
You might try "export -> Java -> jar". This only packages your own code. If you don't have any depended libraries of you own code (expect storm dependencies) this should work. Otherwise, you need to include those manually into your jar (or deploy them on all node in you cluster in the default storm-lib directory). Using maven is a good alternative. However, it's more complicated as it can be explained here in short. Please refer to the maven manual first. -Matthias On 07/16/2015 02:25 PM, Nikos Koukos wrote: > No. I saw that a lot of people refer to this but i couldnt understand > how can i do this.
