-----------------------------------
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.
