Benjamin Teke commented on YARN-10833:
--------------------------------------
[~gandras], thanks for the review. Fixed the test issues, refactored the config
collection, it should be more resilient to NPEs now. As for why the default
changed: the DENY came from the XFrameOptionsFilter but HttpServer2 uses
SAMEORIGIN. This however only impacts the UTs, as yarn-default.xml already
overrode the DENY with SAMEORIGIN.
