             Summary: ShareConsumer HB UnsupportedVersion msg mixed with 
Consumer HB
                 Key: KAFKA-18135
                 URL: https://issues.apache.org/jira/browse/KAFKA-18135
             Project: Kafka
          Issue Type: Bug
          Components: consumer
            Reporter: Lianet Magrans


UnsupportedVersion error is handled in the parent 
AbstractHeartbeatRequestManager, so used by consumer and share consumer. If a 
share consumer gets the errors, it will end up with a msg that is currently 
specific to consumer

[https://github.com/apache/kafka/blob/6fd951a9c0aa773060cd6bbf8a8b8c47ee9d2965/clients/src/main/java/org/apache/kafka/clients/consumer/internals/AbstractHeartbeatRequestManager.java#L384-L386]

One option could be to handle the UnsupportedVersion separately in the existing 
handleSpecificError (note that the unsupported version for consumer may also 
end up containing a msg specific to SubscriptionPattern not supported in HB v0, 
if regex is used without the required v1)
