> Key: SPARK-25732
> URL: https://issues.apache.org/jira/browse/SPARK-25732
> Project: Spark
> Issue Type: Improvement
> Components: Deploy
> Affects Versions: 3.1.0
> Reporter: Marco Gaido
> Priority: Major
>
> As of now, application submitted with proxy-user fail after 2 week due to the lack of token renewal. In order to enable it, we need the the keytab/principal of the impersonated user to be specified, in order to have them available for the token renewal.
> This JIRA proposes to add two parameters {{--proxy-user-principal}} and {{--proxy-user-keytab}}, and the last letting a keytab being specified also in a distributed FS, so that applications can be submitted by servers (eg. Livy, Zeppelin) without needing all users' principals being on that machine.
