Subject: Re: Nifi cluster features - Questions

Chakri,

Glad you got site-to-site working.

Regarding the data distribution, I'm not sure why it is behaving that way. I just did a similar
test running ncm, node1, and node2 all on my local machine, with GenerateFlowFile running
every 10 seconds, and Input Port going to a LogAttribute, and I see it alternating between
node1 and node2 logs every 10 seconds.

Is there anything in your primary node logs (primary_node/logs/nifi-app.log) when you see
the data on the other node?

-Bryan

Chakri,

Would love to hear what you've learned and how that differed from the
docs themselves.  Site-to-site has proven difficult to setup so we're
clearly not there yet in having the right operator/admin experience.

Thanks
Joe
