Hi @Ani1991 ,

Suspecting Kerberos related parameters are incorrectly configured in the Kafka service repo in Ranger.

Can you please try the below solution :

-- Ranager Admin UI > edit kafka service repo cm_kafka > Add configs in "Add New Configurations"

-- Add below configs. (Change the config accordingly) for protocol

bootstrap.servers <kafkaBroker>:Port

security.protocol SASL_PLAINTEXT

sasl.mechanism GSSAPI

kafka.keytab <keytab>

kafka.principal <prinicipal>

This config needs a kafka keytab  path , copy kafka keytab to ranger admin host with ranger:ranger permissions set.
