Summary: Offset commit failure after broker upgrade to 2.0
Key: KAFKA-7403
URL: https://issues.apache.org/jira/browse/KAFKA-7403
Project: Kafka
Issue Type: Bug
Components: core
Reporter: Jon Lee
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:java}
2018/09/11 19:34:52.814 ERROR Failed to commit offsets. Exiting.
org.apache.kafka.common.KafkaException: Unexpected error in commit: The server

{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

{code}
And I was able to reproduce the error by passing KAFKA_0_11_0_IV2 as the
ApiVersion (the second parameter) to the constructor of GroupMetadataManager in
GroupMetadataManagerTest.scala.
[~vahid], can you take a look if this is indeed an issue?
