JMS warning in services log

[Harsh Suri]

After setting up and going through multiple iterations, I am finally able to get everything up and running on a RHEL server.  But I am consistently getting the following warning.  If I understand correct JMS points to a message-driven-channel-adapter(basically Active MQ server - which I am running on the same server for a dev environment - not production). The feed is created successfully and I am able to do all operations (therefore it would appear it successfully fetches the messages) and my system is working fine. However i can see the following line appearing in my kylo-services logs (likely thrown by the tomcat server). 

Can anyone shed some light how can I avoid this warning or more importantly how does it affect the system?

Hi Harsh,

This error message is related to Kylo receiving the provenance events from NiFi. What version of Kylo are you running?

Here's a couple things to try:

1) Go to the ActiveMQ UI (http://localhost:8161). Go to the Queues page and purge the thinkbig.* queues. The default username / password is admin / admin.

2) Run the following command and then restart nifi and repeat #1:

/opt/kylo/setup/nifi/update-nars-jars.sh

3) Your download of Kylo may have been corrupt. Try re-downloading and re-installing Kylo.
