------------------------------------
Summary: Use single error code for offset commit response
Key: KAFKA-1602
URL: https://issues.apache.org/jira/browse/KAFKA-1602
Project: Kafka
Issue Type: Bug
Reporter: Guozhang Wang
As discussed with Joel offline, today the offset commit response contains an
error code for each partition, but the error code will be actually the same
across all partitions except it is failed due to metadata-size-too-large. This
is because only one partition-append is involved for committing the offsets.
Hence we do not need to use a per-partition error code in the response.
Note that this will be a protocol change and hence we need to bump up the
response version number.
