aneesh-joseph opened a new pull request #9044:
URL: https://github.com/apache/airflow/pull/9044
---
When the spark submit hook's `on_kill` is called, it tries to kill the yarn
app, but doesn't do a kinit even if the keytab and principal is supplied. This
would mean that the `yarn applicaition -kill <app id>` will fail when yarn
needs kerberos authentication, and the app will continue to run.
This change tries to do an explicit `kinit` before killing the YARN app(if
keytab and principal are available).
