Íñigo Goiri commented on HDFS-14374:
------------------------------------
Thanks [~crh] for the patch; a few comments:
* Can you do an static import for assertEquals()? The rest may use the whole
syntax but I think we should start using just assertEquals().
* The expected value should be the first parameter for assertEquals().
* For the initialization of {{TestDelegationTokenSecretManager()}} can we use
values like: {{TimeUnit.DAYS.toMillis(7)}}?
* In the javadoc for {{getCurrentTokensSize()}} we should say that cancelled
tokens don't count. Basically describe what we are testing in
{{testDelegationTokenCount()}}.
