NIFI connecting to Activemq
What am I doing wrong with hooking up my activemq jms get template? I put
stuff into the activeMQ and NIFI wont get it. Using 0.4.1.

RE: NIFI connecting to Activemq
Posted by pr...@wipro.com.
Hi,
One non-intuitive step that is required in NiFi is that you have to log into the Nifi web UI and "start" the data flow for NiFi to start processing messages. To "start" the data flow, you have to press the red coloured "play" icon on the top of the web UI, located below the menu items. The URL for the web UI shows up in the logs/nifi-app.log file when the NiFi server starts.
I haven't tried with ActiveMQ and NiFi, but have tried reading a File, processing with NiFi and sending to Apache Spark. When I forget to press the "play" button, Spark is not even able to connect to NiFi.
Regards,
Prajod

Christopher,
Is there any error/feedback showing up in the UI or in the logs?
Thanks

Thanks for the update. Do you have suggestion what I should set my

Chris,
Thanks for sending the screenshot. The NullPointerException is
trivially reproduced using your settings. I didn't even need a JMS
server to cause it.
Have created a JIRA for this: https://issues.apache.org/jira/browse/NIFI-1378
Thanks!
Joe

Well, you URL is malformed, since it should be of form protocol://host:port. Just look at any AMQ sample out there on the web. The part that worries me is the NPE and nothing in the logs. Did you try Joe's suggestion and enable Debug level logging?

Those logs came from a completely new restart with cleared logs.
If have an ActiveMQ topic setup. What should each field have in it if it is
running locally and using port 61613? I think maybe the NPE is related to
bad network connection with my activeMQ. Can't find examples out there.

Are you sure you are providing the correct logs? I can’t see a single mention of JMS nor any stack traces which would definitely be there given what you see in UI.
Also, the fact that you see NPE is definitely a bug that we have to fix (user’s should never see NPE), so that can be filed. What I am trying to figure out is the condition that triggers it. May be if you shut down NIFI, delete all the logs and restart so you can get a fresh data. . .

Chris,
Ok. Can you take a look in the <nifi>/logs/nifi-app.log and see if there
is a stack trace for the NullPointerException included?
If not please add the following to your logback.xml and after 30 seconds or
so it should start giving you the stack traces. A stacktrace for the NPE
would be really useful in pinpointing the likely issue. Also please share
the config details of GetJMSQueue processor that you can.
<logger name="org.apache.nifi.processors.standard.GetJMSQueue"
level="DEBUG"/>
Thanks
Joe
