> I am currently trying broker upgrade from 0.11 to 2.0 with some patches including KIP-211/KAFKA-4682. After the upgrade, however, applications with 0.10.2 Kafka clients failed with the following error:

> {code}
> From my reading of the code, it looks like the following happened:
> # The 0.10.2 client sends a v2 OffsetCommitRequest to the broker. It sets the retentionTime field of the OffsetCommitRequest to DEFAULT_RETENTION_TIME.
> # In the 2.0 broker code, upon receiving an OffsetCommitRequest with DEFAULT_RETENTION_TIME, KafkaApis.handleOffsetCommitRequest() sets the "expireTimestamp" field of OffsetAndMetadata to None.
> # Later in the code path, GroupMetadataManager.offsetCommitValue() expects OffsetAndMetadata to have a non-empty "expireTimestamp" field if the inter.broker.protocol.version is < KAFKA_2_1_IV0.
> # However, the inter.broker.protocol.version was set to "1.0" prior to the upgrade, and as a result, the following code in offsetCommitValue() raises an error because expireTimestamp is None:
> {code:java}
> value.set(OFFSET_VALUE_EXPIRE_TIMESTAMP_FIELD_V1, offsetAndMetadata.expireTimestamp.get){code}
>
> Here is the stack trace for the broker side error

> [~vahid], the error was from the code added for KAFKA-4682. Can you take a look if this is indeed an issue?
