Subject Re: Nothing in rabbitMQ queue from Publish AMQP processor
Date Thu, 08 Dec 2016 13:00:15 GMT
Yes absolutely Oleg. I will try to figure out how to make my rabbitMQ
queues explicitly active. I'll need to dig into that because it is not
plainly obvious to me how / if that needs to be done. I'll dig for that.

I am using NiFi 0.6.1.

Cheers and thanks again,
