Daryn Sharp commented on HDFS-3654:
-----------------------------------
I like the new {{NameNode#verifyToken}}, but it does a synchronized invocation
of {{namesystem.getDelegationTokenSecretManager().verifyToken}}. There's an
existing synchronized {{FSNameSystem#verifyToken}}. You may want to streamline
all of them. I'd lean towards eliminating the {{FSNameSystem#verifyToken}}
since it only appears to be called by {{JspHelper#getUGI}}.
> TestJspHelper#testGetUgi may fail
