I'm using the https://github.com/lhotari/pulsar-release-validation to
validate the Pulsar, and I found the sink doesn't work:

```

+ docker exec -i cassandra31 cqlsh localhost

+ cat

+ bin/pulsar-admin sink create --tenant public --namespace default --name
cassandra-test-sink --sink-type cassandra --sink-config-file
/tmp/tmp.Ilt8S9hK5k/apache-pulsar-4.2.0/examples/cassandra-sink.yml
--inputs test_cassandra

Internal Error updating function at the leader


Reason: Internal Error updating function at the leader

+ kill_processes

+ set +xe

cassandra31

```

Thanks,
Zixuan
