Koji Kawamura commented on NIFI-4350:
-------------------------------------
The changes for NIFI-4323 removes Re-login period parameter and the Kerberos
ticket renewal thread from NiFi. Once NIFI-4323 is resolved, this issue should
be addressed, too.

> Remove relogin period parameter from Hadoop processors
> ------------------------------------------------------
>
> Key: NIFI-4350
> URL: https://issues.apache.org/jira/browse/NIFI-4350
> Project: Apache NiFi
> Issue Type: Bug
> Components: Extensions
> Reporter: Pierre Villard
>
> Right now, in Hadoop processors, there is a re-login period parameter that
> will define when the Kerberos ticket must be renewed by the processor. This
> re-login method will not take into account the lifetime of the generated
> ticket as the Hadoop library does (when requiring a new ticket, one will be
> actually generated only after 80% of the current ticket lifetime).
> With the current situation, in very specific sets of parameters for relogin
> period, ticket lifetime and processor scheduling, we can be in a situation
> where we try to execute the code without actually renewing the ticket. The
> re-login parameter / code should be removed to rely on the one provided by
> the underlying Hadoop library.
> Workaround is to lower the re-login period parameter.
