Get the latest offsets in SSL Enabled Kafka via CMD

I have being using the below CMD to get the latest offsets in from a Kafka Queue which has plain-text port open

kafka-run-class.sh kafka.tools.GetOffsetShell --broker-list server:9092 --topic sample_topic --time -1

But, now we only have the SSL port open, so I tried passing the SSL details as a property file 

kafka-run-class.sh kafka.tools.GetOffsetShell --broker-list server:9093 --topic sample_topic --time -1 --consumer-config /path/to/file

Getting the below error - 

Exception in thread "main" joptsimple.UnrecognizedOptionException: consumer-config is not a recognized option

How do I pass the SSL details to this command? These are all the available arguments for kafka-run-class.sh kafka.tools.GetOffsetShell

--broker-list <String: hostname:and port,...,hostname:port>                
--max-wait-ms <Integer: ms>            
--offsets <Integer: count>             
--partitions <String: partition ids>   
--time <Long: timestamp/-1(latest)/-2             
--topic <String: topic>
Solution

  • Unfortunately kafka.tools.GetOffsetShell only supports PLAINTEXT connection. This tools is not used a lot and nobody has bothered updating it.

    Depending on your use case, you have a few options:

    • Use the kafka-consumer-groups.sh tool: Assuming you have a consumer group consuming from that topic, this tool display the log end offsets of each partitions

    • Patch kafka.tools.GetOffsetShell: It's realtively easy to add support to secured connections bby reusing logic from the other tool. If you do so, consider sending a patch to Kafka =)

    • Write a tiny tool that calls Consumer.endOffsets()

    • Use kafka.tools.DumpLogSegments: As a last resort this tool can also be used to find the last offset
