My availability this week is somewhat intermittent, but I will try to dig 
deeper later on

My situation appears to be different from this one. There is no bad header 
error message exhibited in their case, and it's definitely there every time in 
mine. Additionally, it appears that I do indeed already have a non-Guest user 
with configure/write/read privileges.

That bad header notification may be key, but I cannot determine why that is 
being triggered with my upgraded version of NiFi.

Basically my next question would be if admin-wise the new user had been given 
the correct permissions as I believe you are experiencing the symptoms 
described in the following thread 
http://stackoverflow.com/questions/26811924/spring-amqp-rabbitmq-3-3-5-access-refused-login-was-refused-using-authentica

Let me know

Hi Oleg. The RabbitMQ version is unchanged. I created a user called test, with 
its own password. I endeavor to connect as that user from PublishAMQP.  Thanks 
very much for looking more closely at this. -Jim

James, while I am looking couple of questions.
1. Did you actual RabbitMQ version has changed since you used NiFi 0.6?
2. Are you using default guest/guest user/password to connect?

Cheers
Oleg

I can certainly share germane pieces from it, Oleg.

Background: NiFi version is 0.7.1. RabbitMQ is 3.6.6. Erlang is 17.5-1.

I had recently upgraded my NiFi from 0.6.x to 0.7.1. My broker log shows 
successful connections without the error report when I was still 0.6.x. Since I 
upgraded I have not been able to connect with success.

Thanks in advance for your help. I am very interested in why I seem to be 
getting this bad header message now. -Jim

James, any chance you can provide stack trace from the logs?
