Unable to start or stop a process in NiFi

Unable to start or stop a process in NiFi

I stopped a running process in NiFi 0.4.1 to make a configuration change, but I am unable to make an edit or re-start the process. It seem stuck waiting for a thread to finish. How do I debug this situation? I've looked at nifi-app.log, searched for that process name, but did not see anything of value. I ran ps -eLf hoping to see a thread with Solr in the name, but I didn't find that either. Here is a picture showing the lack of a "start" or "edit configuration" options.

What else can I do to troubleshoot this problem before restarting the nifi process on this machine?

Thanks for reporting it and for providing the stack traces. Very helpful. I've filed an Apache NiFi JIRA for it https://issues.apache.org/jira/browse/NIFI-1417

Vlad, at this point please go into NiFi's bin directory and execute nifi.sh dump command. Send those logs through.
