Not sure about the python sample, but in general, the ShellBolt looks for the files in jar, is the splitsentence.py file in the jar you are producing?

I have followed the instructions during installation and built my package successfully with maven. My storm version is 1.0.3 and my python version is 2.7.13. I ran the ExclamationTopology and some of my own code which does not need multi-language support and it works like a charm. I tried putting file in different locations and changing the relative path, but still it is not working. I am not able to understand why the multi-lang support in storm is not working. Any help with this is greatly appreciated. Thanks and Regards, Sitakanta Mishra
