Question on support for hadoop delegation token based authentication for webhdfs requests

[Sourav Mazumder <so...@gmail.com>]

Hi All,

Say I have a hadoop cluster which has security enabled using Hadoop
delegation token. Now I need to access some from hdfs using webhdfs client.

In this case does the client code need to manage the Hadoop delegation
token or that would be automatically taken care of by Knoix ?

In my understanding Knox should take care of this and the webhdfs client
should not ideally get bothered by internal security implementation of
hadoop cluster (whether it is based on simple security, kerberos or hadoop
delegation token). However wanted to get a confirmation.

Regards,
Sourav
