On the worker machine, do you have Python installed? You can check by running "python -V". You need to ensure you're using the same $PATH as whatever environment is running your Storm supervisor/worker. From the exception stack trace, it looks like your ShellBolt does not see a python interpreter on the $PATH, therefore it can't run your Python bolt.
At least, that's how I read "Caused by: java.io.IOException: Cannot run program "python" (in directory "/tmp/5f3c8318-14da-4999-a974-584a9d200fdb/supervisor/stormdist/mongo_20140528_02 -1-1401786854/resources"): error=2, No such file or directory".
