[jira] [Commented] (HADOOP-7829) Delegation token manager should support token store abstraction

    [ https://issues.apache.org/jira/browse/HADOOP-7829?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13152206#comment-13152206 ] 

Owen O'Malley commented on HADOOP-7829:
---------------------------------------

I'm missing the purpose of this. Is it related to wanting an abstract interface so that servers like the JobTracker to renew and cancel the tokens, like MAPREDUCE-2764?

> There are several issues with the interfaces in .20 that make it difficult to incorporate this as extension currently (see HIVE-2467). The plan is to port relevant changes to Hadoop so that future versions of the shim in Hive (or projects with similar needs) are easier to implement.
