SSL Configuration for Kafka Producer

Hello
I've configured SSL for broker (named kafka1) and producer based on following link: https://www.vertica.com/docs/9.2.x/HTML/Content/Authoring/KafkaIntegrationGuide/TLS-SSL/KafkaTLS-SSLExamplePart3ConfigureKafka.htm).
unlike the broker, the producer hasn't been configured successfully in producer.properties file. Because, there is Kerberos authentication service with following configuration and I can't set security.protocol = SSL as mentioned in above link:
security.protocol=SASL_PLAINTEXT
sasl.mechanism=GSSAPI
sasl.kerberos.service.name=kafka
in order to produce data to kafka this command is used: kafka-console-producer.sh --broker-list kafka1.sgi.ir:9093 --topic test1kafka1 --producer.config /home/pskafka/kafka_2.12-2.4.0/config/producer.properties. But, due to lack of SSL value in security.protocol parameter, errors are generated.
Finally, The question that I have is how can set ssl in producer.properties configuration file?
An image of producer.properties configuration file has been attached.

Can you share the version of Vertica you're using? Support for SASL+SSL was added in 9.3.1. However, the only sasl.mechanism supported is PLAIN. There are also some limitations with KafkaExport.
https://www.vertica.com/docs/10.0.x/HTML/Content/Authoring/KafkaIntegrationGuide/AuthenticatingWithKafkaUsingSASL.htm
Change location props.put (SslConfigs.SSL_KEYSTORE_LOCATION_CONFIG, "/var/private/ssl/kafka.client.keystore.jks");
Now it should work.
