Logstash input with Kerberos Kafka Stream


I'm trying to create a logstash pipeline with kafka input plugin, kafka streams are protected with kerberos security. Provided configuration settings for jaas.conf, krb5.conf, and .keytab file, getting below error. 'Trace' on doesn't help much with the error message.

Any ideas?
