I am currently using celery default prefork for concurrency and I want to use Eventlet.
I tried to install Eventlet and used it for concurrency, but I am getting following error:
[2017-01-01 04:11:14,233: ERROR/MainProcess] consumer: Cannot connect to amqp://application:**@rabbit:5672//: [Errno -2] No address found.
But it is working good with default prefork and I could execute jobs async.
I am currently using django 1.10 and Celery 4.0.1
-------------- celery@worker v4.0.1 (latentcall)

can anyone help please, I could not get the answers googling.
Please us me know, if anyone have any questions.
Not sure what I am missing
"No address found" looks like an error with DNS resolution. If you can resolve the address of your rabbitmq server, the problem may lie with Eventlet.
If you're using Eventlet 0.20.0, it looks like that might break DNS resolution. See: https://github.com/nameko/nameko/issues/392
If that's the case, maybe you can use a different version of eventlet with something like pip install --upgrade eventlet==0.19.0 or pip install --upgrade eventlet==0.20.1.
