> Key: LENS-1514
> URL: https://issues.apache.org/jira/browse/LENS-1514
> Project: Apache Lens
> Issue Type: Improvement
> Components: client, server
>Reporter: Barun Kumar
>Assignee: Barun Kumar
>Priority: Major
>
> As part of LENS-1509, we have added Spnego authentication based on Kerberos
> to lens. This will work in client-server mode. But this approach will cease
> to work in a hadoop cluster in which user is using lens client in a mapred
> job(such as oozie java action) since there will not be keytabs in the hadoop
> cluster. The authentication in hadoop work on concept of delegation
> token([https://blog.cloudera.com/blog/2017/12/hadoop-delegation-tokens-explained/).]
> Here we are introducing delegation token auth in lens. We are piggybacking on
> HDFS to do authentication by passing it's token and performing a filesystem
> operation.
>
> We will add proper delegation token implementation as future improvement.
