Prabhu Joseph commented on HADOOP-16354:
----------------------------------------

Thanks [~eyang] for reviewing.

Have modified AuthFilter to extend ProxyUserAuthenticationFilter so that doas 
support is provided for NameNode UI + WebHdfs. Both accepts case insensitive 
doas flag. 

Have tested both 2.1 and 2.2 test cases, it works fine.

 

> Enable AuthFilter as default for WebHdfs

> HADOOP-16314 provides an generic option to configure 
> ProxyUserAuthenticationFilterInitializer (Kerberos + doAs support) for all 
> the services. If this is not configured, AuthenticationFIlter is used for 
> NameNode UI and WebHdfs. Will enable AuthFilter as default for WebHdfs so 
> that it is backward compatible.
