Andras Beni commented on LIVY-792:
----------------------------------
[~soundhearer] I recommend contacting Cloudera support if you have an issue
with Livy in a CDH distribution. In this case it is especially important
because kerberos relogin in CDH's Livy differs from Apache Livy 0.6.0.
In the meantime you might want to check if you run into
https://bugs.openjdk.java.net/browse/JDK-8186576
> The spark job cannot be submitted due to the expiration of Livy Keytab

> Project: Livy
> Issue Type: Bug
> Components: Server
> Affects Versions: 0.6.0
> Environment: CDH7.1.1
> Reporter: Leping Huang
> Priority: Blocker
>

> will expire every four days. As a result, spark jobs cannot be submitted
> through Livy. I need to restart Livy every time to solve the problem.
