Subject [jira] [Commented] (HDFS-9525) hadoop utilities need to support provided delegation tokens
Date Tue, 05 Jan 2016 22:02:39 GMT

    [ https://issues.apache.org/jira/browse/HDFS-9525?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15083924#comment-15083924
] 

Allen Wittenauer commented on HDFS-9525:
----------------------------------------

Oozie was just an example.

If I'm firing off several jobs at once via threading, being able to set this as config instead
of an env var is significantly easier because it means I don't have to lock around it.

> When using the webhdfs:// filesystem (especially from distcp), we need the ability to
inject a delegation token rather than webhdfs initialize its own.  This would allow for cross-authentication-zone
file system accesses.
