Zach York commented on LIVY-549:
--------------------------------
If you're using impersonation with livy, wouldn't the job have the Livy
principal and keytab? Does that not work? What error are you receiving?
Btw, this is probably a better question for the user or dev lists.

> Key: LIVY-549
> URL: https://issues.apache.org/jira/browse/LIVY-549
> Project: Livy
> Issue Type: Question
> Components: API, Batch
> Affects Versions: 0.5.0
> Reporter: gejx
> Priority: Blocker
>
> I have already used to try spark-submit way with --principal and --keytab
> parameters. This way was successd.
> I have a Spark job where part of the work done on the executors includes
> POSTing to a SPNEGO-enabled REST API endpoint, and unless I'm mistaken, when
> Spark is running a job as a proxy user, the doAs() chain doesn't have the
> necessary credentials to actually do a SPNEGO negotiation.
> How can I use Livy to achieve this function. Thank You.
> spark version:2.3.1
