QUESTION
I have a server where I installed a RabbitMQ broker and two Celery consumers (main1.py and main2.py) both connected to the same broker.
In the first consumer (main1.py), I implemented a Celery Beat that sends multiple times a different task on a specific queue:
...ANSWER
Answered 2017-May-11 at 16:28Here's what is happening. You have two workers A
and B
one of which also happens to be running celery beat (say that one is B
).
- celery beat submits
task.beat
to the queue. All this does is enqueue a message in rabbit with some metadata including the name of the task. one of the two workers reads the message. Both A and B are listening to the same queue so either may read it.
a. If A reads the message it will try to find the task called
tasks.beat
this blows up because A doesn't define that task.b. If B reads the message it will successfully try to find the task called
tasks.beat
(since it does have that task) and will run the code.tasks.beat
will enqueue a new message in rabbit containing the metadata fortasks.print
.- The same problem will again occur because only one of A and B defines
tasks.print
but either may get the message.
In practice, celery may be doing some checks to throw an error message earlier but I'm fairly certain this is the underlying problem.
In short, all workers (including beat) on a queue should be running the same code.
