---------------------------------
Summary: Multi noded with kraft combined mode will fail shutdown
Key: KAFKA-14287
URL: https://issues.apache.org/jira/browse/KAFKA-14287
Project: Kafka
Issue Type: Bug
Components: kraft
Affects Versions: 3.3.1
Reporter: Luke Chen
Assignee: Luke Chen
Multiple nodes with kraft combined mode (i.e.
process.roles='broker,controller') can startup successfully. When shutdown in
combined mode, we'll unfence broker first. When the remaining controller nodes
are less than quorum size (i.e. N / 2 + 1), the unfence record will not get
committed to metadata topic successfully. So the broker will keep waiting for
the shutdown granting response and then timeout error:
