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.
> webhdfs:// needs to support provided delegation tokens

> 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.
