InstanceMetadataProvider hangs on load() 100% reproducible

See original GitHub issue

Hi guys,

Starting from boto3 version 1.10.0 the following code hangs on line 104:

102         t = InstanceMetadataFetcher(timeout=1000, num_attempts=2)
103         provider = InstanceMetadataProvider(iam_role_fetcher=t)
104    ->   creds = provider.load()

Tracing it further it stuck request at: botocore/utils.py:296

                response = self._session.send(request.prepare())

None of 1.9.xxx versions had this issue. Python 3.7.3

When i only run the test.py file i am not getting any error so i don’t think this error is related to boto3. As you have already mentioned that this error can only be seen with kubernetes , i am assuming this is something related to kubernetes. I don’t have much knowledge about kubernetes. I would recommend posting on their github repo .

seeing this issue seems like if we reduce timeout to 1 sec, the process seems to be done. timeout as 1000 making it look like third line is unreachable, but anyway why are we waiting for timeout to give a response is the problem.
