Ranger Service test connection failed

[#1]

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

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.
