[jira] [Created] (SPARK-25732) Allow specifying a keytab/principal for proxy user for token renewal

Marco Gaido created SPARK-25732:
-----------------------------------

             Summary: Allow specifying a keytab/principal for proxy user for token renewal 
                 Key: SPARK-25732
                 URL: https://issues.apache.org/jira/browse/SPARK-25732
             Project: Spark
          Issue Type: Improvement
          Components: Deploy
    Affects Versions: 2.4.0
            Reporter: Marco Gaido


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.
