From jaas file I see that the debug=true was added, on the other hand, the debug is not showing up in the producer output, which means that the jaas file provided is not picker up properly.   If you check the kafka-console-producer.sh you'll notice below lines:   # check if kafka_jaas.conf in config , only enable client_kerberos_params in secure mode. KAFKA_HOME="$(dirname $(cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd ))" KAFKA_JAAS_CONF=$KAFKA_HOME/config/kafka_jaas.conf if [ -f $KAFKA_JAAS_CONF ]; then export KAFKA_CLIENT_KERBEROS_PARAMS="-Djava.security.auth.login.config=$KAFKA_HOME/config/kafka_client_jaas.conf" fi Try editing kafka_client_jaas.conf  or also you can try to export using KAFKA_CLIENT_KERBEROS_PARAMS and see if that helps.   Regards, Manuel. ...
