----------------------------------
Summary: Unclear warning due to empty throttled fetch response
Key: KAFKA-9276
URL: https://issues.apache.org/jira/browse/KAFKA-9276
Project: Kafka
Issue Type: Bug
Components: core
Affects Versions: 2.3.0
Reporter: Bob Barrett
With a version 1.0.0 consumer talking to a 2.3.0 broker, the following
WARN-level statement is logged when a request is throttled:
{code:java}
Ignoring fetch response containing partitions [] since it does not match the
requested partitions [topic-29, topic-25, topic-21, topic-17, topic-33]{code}
It appears that the 1.0.0 consumer expects fetch data for all partitions, but
the throttled response is empty, causing an unclear warning message. This may
be a regression from KIP-219, which changed the throttling behavior to return
the empty fetch response.
