Paul Grey commented on NIFI-14059:
----------------------------------
[https://github.com/apache/nifi/pull/9607/files]
I've opened a pull request that adds the needed component properties. A couple
of notes:
* with these properties, the kafka-shared support classes seem to now do the
right thing
* if you're comparing / contrasting previous Kafka component behavior, please
be aware that Java 21 (NiFi 2) does not seem to be compatible with older
SASL/Kerberos mechanisms that worked with Java 8 (NiFi 1). In particular, it
was necessary to add these algorithms to the "permitted_enctypes" in my
Kerberos server config:
** aes256-cts-hmac-sha1-96
** aes128-cts-hmac-sha1-96
* I tested using the new controller service property "Kerberos User Service".
There was an analogous property "Kerberos Credentials Service" that was also
previously available, so I added it as well.
