Jitendra Nath Pandey commented on HADOOP-6580:
----------------------------------------------
This jira adds support to set and get authenticaton method from the UGI.
This feature is used by hdfs and mr to get the authentication method to allow
only kerberos and web authenticated clients to get and renew delegation tokens.
It also introduces a new AuthMethod.WEB enum for authenticated web connections.
> UGI should contain authentication method.
