Yuanbo Liu commented on HADOOP-13718:
-------------------------------------

[~Wancy] Thanks to file this issue. I'd like to fix it in HADOOP-13119. Eric didn't want to
lose discussion there for filing another jira. I'm gonna mark this jira as duplicate. If you
have any suggestion, please let me know. Thanks a lot!

to add DelegationTokenFilter to support proxy user and delegation token authentication.

> This is useful to use DelegationTokenAuthenticationFilter for HADOOP Web Console authentication.
Especially after KNOX-565, all quick link could go through knox and we'll need DelegationTokenAuthenticationFilter
to do the "getDoAsUser" job and call kerberosAuthenticationHandler for us.
