Íñigo Goiri commented on HDFS-14447:
------------------------------------
Thanks [~lukmajercak], I agree on fixing the spaces.
On top of that, a couple comments:
* It would be good to use StringBuilder in
TestRefreshUserMappingsWithRouters#349.
* Use assertNotEquals in TestRefreshUserMappingsWithRouters#318
* In the waitFor you can use TimeUnit to convert between seconds and ms.
* In 331, use the logger and put some message. What about making it debug too?
* Fix style in TestRefreshUserMappingsWithRouters#209
[~shenyinjie] do you mind taking care of those?
