------------------------------------
Summary: NPE in ControllerMetricsManager when upgrading from old
KRaft version
Key: KAFKA-14769
URL: https://issues.apache.org/jira/browse/KAFKA-14769
Project: Kafka
Issue Type: Bug
Affects Versions: 3.4.0
Reporter: David Arthur
Assignee: Jose Armando Garcia Sancio
Fix For: 3.5.0, 3.4.1
In older KRaft versions, we could see a ConfigRecord for a topic config appear
before the TopicRecord in a batch.
When upgrading from an older KRaft version (e.g., 3.1), the latest code in the
KRaft controller hits an NPE when it encounters a ConfigRecord for a topic
config before the TopicRecord. This was introduced relatively recently by
KAFKA-14457
