Subject Re: Using RabbitMQ Sinks
Date Mon, 08 Aug 2016 19:41:46 GMT
The error you've reported is coming from the RabbitMQ library. I guess the
problem is that the queue already exists, and it has been created with
different parameters [1].
Either you overwrite the "protected void setupQueue()" method in Flink to
match the params with the existing queue, or you use a different queue name.

I hope that helps.
