------------------------------------
Summary: 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.
