I remember having this issue a long time ago. It's amazing it still lingers. I don't remember my workaround but perhaps the dirty way to clean up is to comment out the kill and shutdown statements http://stackoverflow.com/questions/16658779/twitter-storm-example-running-in-local-mode-cannot-delete-file

Hi @Artem Ervits I came across and tried the suggestion in that page but still encountered the same errors after commenting out the kill and shutdown statements... the error appears to be caused during the submission / startup stage?

Please try to match your pom.xml versions to your cluster, I noticed you're using Storm 2.0 dependency
