-------------------------------------

             Summary: DumpLogSegments cannot print 
ConsumerGroupRegularExpression record
                 Key: KAFKA-18234
                 URL: https://issues.apache.org/jira/browse/KAFKA-18234
             Project: Kafka
          Issue Type: Bug
            Reporter: Kuan Po Tseng
            Assignee: Kuan Po Tseng


When using new consumer protocol and call subscribe by invoking 
SubscriptionPattern.

 
{code:java}
consumer.subscribe(new SubscriptionPattern("test*"));
{code}
Then use kafka-dump-log to check the consumer_offsets log

 
{code:java}
./bin/kafka-dump-log.sh --offsets-decoder --files
{code}
Unknown record type 16 at offset 5 error shows up. We should add 
`ConsumerGroupPartitionMetadataKey` and `ConsumerGroupPartitionMetadataValue` 
to DumpLogSegments to fix this error.

 
{code:java}
| offset: 5 CreateTime: 1734107666076 keySize: 21 valueSize: 20 sequence: 5 
headerKeys: [] key: Unknown record type 16 at offset 5, skipping.{code}
