Issue 1:
Checklist

I have included the output of celery -A proj report in the issue.

(if you are not able to do this, then at least specify the Celery

version affected).

I have verified that the issue exists against the master branch of Celery.

software -> celery:4.2.1 (windowlicker) kombu:4.2.1 py:3.6.6
billiard:3.5.0.4 py-amqp:2.3.2
platform -> system:Darwin arch:64bit imp:CPython
loader -> celery.loaders.app.AppLoader
settings -> transport:amqp results:disabled

accept_content: ['json']
broker_transport_options: {
'region': 'eu-west-1'}
broker_url: 'amqp://guest:********@localhost:5672//'
config: <decouple.AutoConfig object at 0x10dc81208>
settings: *
task_always_eager: False
task_default_queue: *
task_ignore_result: True
task_serializer: 'json'
timezone: 'UTC'
include: *

Steps to reproduce

Send a unregistered task to Celery configured with SQS broker.

Expected behavior

The task should fail once with KeyError.

Actual behavior

The task failed with KeyError but was was still in SQS with in flight status and was constantly being picked up by the worker, stuck in an infinite loop.

This generated over 1k events in Sentry, even though the incorrect task was sent only once, all with the same error message:

Received unregistered task of type KeyError('Foobar',).
The message has been ignored and discarded.

Did you remember to import the module containing this task?
Or maybe you're using relative imports?

Please see
http://docs.celeryq.org/en/latest/internals/protocol.html
for more information.

The full contents of the message body was:
*

To fix this, I had to clear the SQS queue, which worked as expected.

AWS docs in regards to 'in flight' messages (A message is considered to be in flight after it's received from a queue by a consumer, but not yet deleted from the queue.) helped me understand the problem (the task wasn't acknowledged back to SQS), but I'm still not sure wether this is an SQS limitation or a Celery bug.

I am aware of:

#4002

https://stackoverflow.com/questions/41300209/celery-sqs-duplication-of-tasks-sqs-visibility-timeout

http://docs.celeryproject.org/en/latest/getting-started/brokers/sqs.html?highlight=sqs#caveat

but, I don't use ETA/countdown/retry anywhere so I'm not sure if this is the problem / limitation.

I tried debugging this myself but I figured I might as well ask here to be sure I understand what happened and so people can search for this in the future.

Issue 2:
Looks like sphinsx emmits a lot of warning during documentation build.
