[jira] [Commented] (HADOOP-8779) Use tokens regardless of authentication type

    [ https://issues.apache.org/jira/browse/HADOOP-8779?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13450794#comment-13450794 ] 

Daryn Sharp commented on HADOOP-8779:
-------------------------------------

The security framework currently only uses tokens for authz if and only if kerberos is the auth method.  With security "off", this introduces multiple code paths with added complexity and reduced code coverage.  Pre-commit integration tests cannot verify that authz/tokens work, so devs w/o access to a secure cluster may unexpectedly break tokens.

The change to allow tokens with simple auth must be backwards compatible.

> Security is a combination of authentication and authorization (tokens).  Authorization may be granted independently of the authentication model.  Tokens should be used regardless of simple or kerberos authentication.
