Manikumar commented on KAFKA-7547:
----------------------------------
Since Kerberos ticket expiration times are typically short, repeated logins are
required to renew the tickets.
> Avoid relogin in kafka if connection is already established.

> Key: KAFKA-7547
> URL: https://issues.apache.org/jira/browse/KAFKA-7547
> Project: Kafka
> Issue Type: Improvement
> Components: security
> Reporter: Pradeep Bansal
> Priority: Major
>
> I am new to kafka and may be there are ways already there for my requirement.
> I didn't find a way so far and hence I though I will post it here.
> Currently, I observed that kafka periodically tries to renew kerberos token
> using kinit -R command. I found that I can set
> sasl.kerberos.min.time.before.relogin and change default from 1 minute to 1
> day max. But in my case I am not clear on why renew is even required.
>
> If it is not really required is there a way to turn it off?
