-----------------------------------

             Summary: HadoopDBCPConnectionPool doesn't use KerberosUserService
                 Key: NIFI-12467
                 URL: https://issues.apache.org/jira/browse/NIFI-12467
             Project: Apache NiFi
          Issue Type: Bug
          Components: Extensions
            Reporter: Matt Burgess
             Fix For: 1.25.0, 2.0.0


NIFI-8978 added some KerberosUserService integration with the 
DBCPConnectionPool implementations, but for HadoopDBCPConnectionPool its values 
are only used during customValidate(). They are not read in onEnabled() and 
will fail when authenticating.

The workaround is to use the Principal and Keytab/Password properties or a 
Keytab Credentials Service instead of a KerberosUserService.
