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.
