Chris Nauroth commented on HDFS-7984:
-------------------------------------
Hi Allen. It's unclear to me what this issue is requesting. Can you please
elaborate? It sounds like you want a customizable hook into the WebHDFS
client's logic for delegation token handling. You mentioned initialization,
but do you also need a hook into renewal and cancellation too?
I'm not sure what kind of use case would motivate this customization. Do you
have some scenario where your process already has a delegation token, and you'd
prefer not to get a new token for WebHDFS? If so, then any further details
about this scenario would be helpful.
Thanks!

> Key: HDFS-7984
> URL: https://issues.apache.org/jira/browse/HDFS-7984
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: webhdfs
> Affects Versions: 3.0.0
> Reporter: Allen Wittenauer
> Priority: Blocker
>
> 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.
