ndeslandes opened a new pull request #10036: [FLINK-14562][Connectors/ 
RabbitMQ]Idle consumer are left behind on closing
URL: https://github.com/apache/flink/pull/10036
 
 
   ## What is the purpose of the change
   
   *This pull request fix the close() method on the RMQSource class to clean 
any consumer that was used in it. This is needed to prevent leaving idle 
consumer of the RabbitMQ cluster*
   
   
   ## Brief change log
   
     - *Use the channel to cancel the active consumer*
     - *Close the channel itself*
     - *Close the connection (was already there)*
   
   
   ## Verifying this change
   
   The close method does not seem to be tested right now and I am not sure how 
to add a test for that.
   This fix clearly fix that bug for us in all of our environment  and I don’t 
think it can break anything else.
