Thanks [~mackrorysd] for the review!
I refactored the test the way you suggested and fixed the checkstyle issues.

tested against eu-west-1, no new issues.

Sean Mackrory commented on HADOOP-15988:


Good stuff. A few nits:
* Can you clean up the checkstyle issues that were raised?
* Most of the code between the 2 tests is shared. Can we refactor that into a 
single test that just tests the same sequence with a different auth value and 
outcome? If that turns out to be messy for some reason it's not a deal breaker, 
but worth a couple of minutes if that's all it takes.

+1 otherwise.
