-----------------------------------

Hello again, after coming back to this problem, I think I found the root cause 
of the issue.

Indeed `hadoop-cos` is somehow related to the problem. On Spark 3.2 It is 
bringing `cos_api-bundle-5.6.19.jar` to the classpath and this jar contains an 
outdated `public-suffix-list.txt` file, with the following contents:

 
{code:java}
// Amazon S3 : https://aws.amazon.com/s3/
// Submitted by Luke Wells <psl-maintain...@amazon.com>
*.s3.amazonaws.com
s3-ap-northeast-1.amazonaws.com
s3-ap-northeast-2.amazonaws.com
s3-ap-south-1.amazonaws.com {code}
The file which the default hostname verifier should be using should come from 
`hadoop-client-runtime-3.3.1.jar`, which has the following contents:
{code:java}
// Amazon S3 : https://aws.amazon.com/s3/
// Submitted by Luke Wells <psl-maintain...@amazon.com>
s3.amazonaws.com
s3-ap-northeast-1.amazonaws.com
s3-ap-northeast-2.amazonaws.com
s3-ap-south-1.amazonaws.com
s3-ap-southeast-1.amazonaws.com
s3-ap-southeast-2.amazonaws.com
s3-ca-central-1.amazonaws.com
s3-eu-central-1.amazonaws.com
... (all regional endpoints) {code}
For some reason, the `public-suffix-list.txt` was picked from 
`cos_api-bundle-5.6.19.jar` on my classpath, not from 
`hadoop-client-runtime-3.3.1.jar`.

Replacing `cos_api-bundle-5.6.19.jar` with a more up-to-date version 
(`cos_api-bundle-5.6.69.jar`) fixed this issue (since it has the same 
`public-suffix-list.txt` than in `hadoop-client-runtime-3.3.1.jar`). Can I 
create a PR to bump this cos_api-bundle on hadoop-cos?
