Hi Flore,   We are blocked due to Co-Processor issue in Kerberos environment. It would be great if you can explain bit detail about the steps you have done for running co-processor in Kerberos Environment.   Below are the few points. a) Which Keytab you have used, whether CM generated keytab or user keytab generated by you? b) Path of your jaas.conf and keytab for Kafka? c) How Kafka Kerberos configuration parameters set?   I am able to execute my coprocessor code in Non Kerberos cluster but in getting error  "org.apache.kafka.common.KafkaException: Jaas configuration not found" while running the code inside the co-processor in Kerberos environment.   Thanks in advance.
