             Summary: OffsetRequest handler does not handle errors
                 Key: KAFKA-523
                 URL: https://issues.apache.org/jira/browse/KAFKA-523
             Project: Kafka
          Issue Type: Bug
          Components: core
    Affects Versions: 0.7.1
            Reporter: David Arthur
            Priority: Minor


There is not error handling in the KafkaRequestHandlers#handleOffsetRequest, as 
a result invalid requests get no data back since they raise an Exception in the 
server.

E.g., I make an OffsetRequest for an invalid partition I get no response on the 
client side, and I see the following exception in Kafka server logs

{code}
kafka.common.InvalidPartitionException: wrong partition 10
