Subject [jira] [Commented] (HDFS-7984) webhdfs:// needs to support provided delegation tokens
Date Mon, 30 Nov 2015 23:11:11 GMT

    [ https://issues.apache.org/jira/browse/HDFS-7984?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15032689#comment-15032689
] 

Allen Wittenauer commented on HDFS-7984:
----------------------------------------

If I understand the code change correctly, I'm sort of surprised this doesn't work:

on user account1:

{code}
hdfs fetchdt /tmp/token
chmod a+r /tmp/token
{code}

on user account2:

{code}
hadoop fs -Dhadoop.token.file=/tmp/token -ls /user/account1
{code}

Both hdfs and webhdfs are failing this simple test.

> 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.
