[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=15127368#comment-15127368 ] 

Jing Zhao commented on HADOOP-8779:
-----------------------------------

Based on the discussion in HDFS-9184, should we continue the work here as a long-term solution? To have token regardless of authentication type can also make multi-tenancy in HDFS easier to build: maybe we can utilize token to indicate the io priority of a job, or more generally the resource that a job can use within HDFS.

> 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.
