Ruslan Dautkhanov commented on SPARK-5493:
------------------------------------------
Thank you [~vanzin]!
I guess a forwardable and/or proxiable Kerberos ticket be used here instead
somehow;
but normally there is a limit for how long a Kerberos ticket can be renewed.
How is this resolved in Livy?
Also the same problem in Apache Zeppelin to implement multitenancy for Spark
