I am trying send messages through kafka producer but getting following error. I am using following command to establish connection.
export KAFKA_OPTS="-Djava.security.auth.login.config=$OSI_HOME/jaas.conf -Djava.security.krb5.conf=$OSI_HOME/krb5.conf"$OSI_HOME/Custom/confluent/bin/kafka-console-producer --topic testTopic --bootstrap-server <server list> --producer.config producer.properties
Here's the JAAS config I am using
KafkaClient { com.sun.security.auth.module.Krb5LoginModule required useKeyTab=true storeKey=true keyTab="[Location of keytabfile]" serviceName="kafka" useTicketCache=true principal="svc_account@REALM"; };
I can see producer was able to connect. But when I try to send messages I get following error.

This may happen due to any of the following reasons: (1) Authentication failed due to invalid credentials with brokers older than 1.0.0, (2) Firewall blocking Kafka TLS traffic (eg it may only allow HTTPS traffic), (3) Transient network issue.

Does anyone know how to resolve this? I tried telnet command for broker list and it's connected so it doesn't seem to be a firewall issue. I can also do kinit from the server so doesn't seem to be an authentication issue.
