Ranger Service test connection failed

Question

Tried testing the ranger service connection and it is getting failed with message "JAAS configuration missing or not correct in Ranger"

Ranger-admin log:

2021-11-16 12:00:58,661 ERROR org.apache.ranger.services.kafka.RangerServiceKafka: <== RangerServiceKafka.validateConfig Error:java.lang.Exception: JAAS configuration missing or not correct in Ranger Kafka Service...bootstrap.servers,security.protocol,sasl.mechanism,kafka.keytab,kafka.principal

Is jaas file created automatically on ranger.?

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 :Portsecurity.protocol SASL_PLAINTEXTsasl.mechanism GSSAPIkafka.keytab kafka.principal This config needs a kafka keytab path , copy kafka keytab to ranger admin host with ranger:ranger permissions set.
