Kafka Configuration Instance Error
While creating the Kafka configuration instance, we are getting following error:
Error connecting to Kafka. Failed to construct kafka consumer. java.lang.IllegalArgumentException: No serviceName defined in either JAAS or Kafka config. No serviceName defined in either JAAS or Kafka config
Pega and Kafka Cluster running in different servers with firewall open for ports in each server. We are using kerberos authentication.
Performed the following in Pega server -
1. Added KafkaClient in wsjass.conf
KafkaClient {
com.sun.security.auth.module.Krb5LoginModule required
useKeyTab=true
useTicketCache=false
keyTab="kafka.keytab"
principal="kafka/[email protected]";
};
2. Placed wsjass.conf in Pega server in location /usr/WebSphere9/AppServer/profiles/Node01/properties/wsjaas.conf
3. Passed JAAS file location as a JVM parameter in Pega - Djava.security.auth.login.config = /usr/WebSphere9/AppServer/profiles/Node01/properties/wsjaas.conf
Please let me know what else must be done or if any corrections to be made.

@HARISH87On Websphere middleware we had to use ibm Krb module, heres our complete setup on 8.3 version:
Dynamic System Setting: Pega-Engine prconfig/dnode/kafka/consumer/sasl.kerberos.service.name/default
Nothing in PRConfig
Two JVM arguments:
-Djava.security.auth.login.config=${APP_DIR}/config/ODL_kafka_client_jaas.conf
-Djava.security.krb5.conf=${APP_DIR}/kerberos/krb5.conf
JAAS file:
KafkaClient { com.ibm.security.auth.module.Krb5LoginModule required credsType=Both principal="*****" useDefaultCcache=false debug=true usekeytab="path/to/keytab/" };
