addisonj opened a new pull request #9387:
URL: https://github.com/apache/pulsar/pull/9387
### Motivation
With the refactor of support azure, a regression occured where the AWS
credentials were fetched once and then used through the entire process.
This is a problem in AWS, where it is commonplace to use credentials
that expire.
### Modifications
The AWS credential provider chain takes care of this
problem, but when intgrating with JClouds, that means we need the
credential Supplier to return a new set of credentials each time.
Luckily, AWS should intelligently cache this so we aren't thrashing the
underlying credential mechanisms.
### Verifying this change
This also adds a test to ensure this isn't broken in the future, it does a
simple validation to ensure that the underlying credentials can change via AWS
SystemPropertyCredentialProvider
