Using CentOS 6 and Stack 2.1:
After a crash, I noticed that I the Supervisor and therefore Storm won’t start up. To fix this, what I did was completely delete the /hadoop/storm/supervisor and /hadoop/storm/worker directories. This fixed the issue and everything started working perfectly.
This issue was related to this bug in Storm:
https://issues.apache.org/jira/browse/STORM-307
Have a good one,
