Zeppelin stuck - keep trying to authenticate kerberos authentication

Hi,

We are experiencing issues with the Spark interpreter and Zeppelin's
behaviour. Whenever we launch a note and we do not have a valid kerberos
ticket, the application keeps trying to authenticate and does not time out.
In this state, the interpreter cannot be restarted, the note cannot be
cancelled. Only a whole application restart works.

Is there any way around how to kill a particular execution, to get out from
this loop?
Thanks
Andras

Re: Zeppelin stuck - keep trying to authenticate kerberos authentication

Posted by András Kolbert <ko...@gmail.com>.

Yes, that would be a solution if I could get the impersonation working. We
need to control the permissions based on sentry and not based on the
service account's keytab file.

spark.yarn.keytab
spark.yarn.principal
