Kafka Broker not starting after enabling ranger

amru — Tue, 22 Oct 2024 14:28:58 GMT

Hi Team,

After enabling ranger in Kafka, I am not able to bring up the Kafka broker instance.

The error is:

[kafka-raft-io-thread]: Encountered fatal fault: Unexpected error in raft IO thread
org.apache.kafka.common.errors.ClusterAuthorizationException: Received cluster authorization error in response InboundResponse(correlationId=0, data=FetchResponseData(throttleTimeMs=0, errorCode=31, sessionId=0, responses=[]), sourceId=155)

Please help resolve this. Thanks in advance.

Hello @amru,

We need the complete log file or a relevant log snippet to understand why Kafka is failing after enabling Ranger.

But you should consider checking,

Check Ranger’s audit logs to see if any access requests were denied, which could help you pinpoint the issue and the specific resource where permissions are lacking.
You should check the Ranger logs for any errors or issues.
Ensure that Kafka policies are synced successfully.
If you are using AD/LDAP, ensure that all users are properly synced with Ranger.

Thank you
