> A recurrent theme in s3a-related JIRAs, support calls etc is "tried upgrading the AWS
SDK JAR and then I got the error ...". We know here "don't do that", but its not something
immediately obvious to lots of downstream users who want to be able to drop in the new JAR
to fix things/add new features
> We need to spell this out quite clearlyi "you cannot safely expect to do this. If you
want to upgrade the SDK, you will need to rebuild the whole of hadoop-aws with the maven POM
updated to the latest version, ideally rerunning all the tests to make sure something hasn't
broken. 
> Maybe near the top of the index.md file, along with "never share your AWS credentials
with anyone"
