Great that we finally get rid of this AWS dependency.
It seems that the dependency actually influenced somehow other dependencies
from Hadoop.
I have a test in the YARN tests which verifies that the web interface is
working. It seems that the change has broken that test now, so most likely the
PR breaks the web interface.
