@Ankit88 ,   For a Java application you need to add the following Kafka property to your producer/consumer configuration: sasl.jaas.config=com.sun.security.auth.module.Krb5LoginModule required useKeyTab=true keyTab="./myuser.keytab" principal="myuser@XYZ.SITE";  Where myuser.keytab is your user's Kerberos keytab.   Cheers, André ...
