             Summary: Improve debuggability of ShellBolt and ShellSpout
                 Key: STORM-266
                 URL: https://issues.apache.org/jira/browse/STORM-266
             Project: Apache Storm (Incubating)
          Issue Type: Improvement
            Reporter: Robert Joseph Evans


ShellBolt and ShellSpout are sometimes difficult to debug, especially when there are multiple instances running in under the same worker.  It would be good to include the name of the bolt/spout in the logged messages, and probably the PID of the sub process too.

In the case of errors it would be good for ShellProcess to try
and get the exit code for the process, up to a timeout, and then get the
contents of stderr.  Also in the case of errors when wrapping the exceptions we probably want to include the name of the bolt/spout and the PID in the
Exception message.
