In the Kafka instance when configured to the kafka host and click on Test Connectivity getting the below error message: 

Error connecting to Kafka. Failed to construct kafka consumer. Could not find a 'KafkaClient' entry in the JAAS configuration. System property 'java.security.auth.login.config' is /local/web/WebSphere855/AppServer/profiles/asp1/properties/wsjaas.conf

We are directly having the Credential Cache file which is referred in the JVM Arg's but in pega its always referring to the jaas config.

-DKRB5CCNAME=file:///apps/test/kerberos/krb5cc_webuser

In our usecase, we don't refer  to refer to the krb5 config or keytab files to configure in the JAAS config file, external system always generate the Credential cache file which we need to refer to it.

Any help would be greatly appreciated.
