2018-12-18 10:06:12 UTC - Victor Li: @David Kjerrumgaard currently, is there a Nar package we can use? we want to try to integrate our NiFi platform with Pulsar.  for now,  we are using kafka as a bridge between nifi and pulsar. But just for our demo.

2018-12-18 10:19:19 UTC - Nicolas Ha: It looks like a kubernetes problem, but asking here just in case someone saw this before.

I had a 1-node kubernetes with my app and pulsar, and I added two more nodes. It then stopped working, and I had exceptions from the client in the logs cannot find “proxy”. I checked the DNS using <https://kubernetes.io/docs/tasks/administer-cluster/dns-debugging-resolution/> - everything looks fine. I rebuilt the three nodes from scratch, using coredns instead of kubedns (with kubespray). It still doesn’t work.
Anyone has a clue what I should look at next?

2018-12-19 03:15:06 UTC - David Kjerrumgaard: @Victor Li I will build you a 1.7 nar file and share it with you ASAP.  The current code in the PR is slated for the 1.9 release of NiFi, but I should be able to back-port it to 1.7
----
2018-12-19 03:33:07 UTC - David Kjerrumgaard: @Victor Li Here is a 1.7.0 compatible NAR file.
----
2018-12-19 03:34:09 UTC - David Kjerrumgaard: @Victor Li Please let me know if you have any issues with it. I don't have a 1.7 environment readily available to test it with, but it should work. I apologize in advance if you have issues with it
