Luke Chen commented on KAFKA-14287: ----------------------------------- [~dengziming] [~jsancio] [~hachikuji] , any thoughts about this issue? Firstly, I'd like to confirm this is the correct use case for multi combined nodes. If so (I assume), we can brainstrom for a good solution. Othewise, we just document that we don't support it. > 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 > Priority: Major > > 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: > > {code:java} > 2022-10-11 18:01:14,341] ERROR [kafka-raft-io-thread]: Graceful shutdown of > RaftClient failed (kafka.raft.KafkaRaftManager$RaftIoThread) > java.util.concurrent.TimeoutException: Timeout expired before graceful > shutdown completed > at > org.apache.kafka.raft.KafkaRaftClient$GracefulShutdown.failWithTimeout(KafkaRaftClient.java:2408) > at > org.apache.kafka.raft.KafkaRaftClient.maybeCompleteShutdown(KafkaRaftClient.java:2163) > at org.apache.kafka.raft.KafkaRaftClient.poll(KafkaRaftClient.java:2230) > at kafka.raft.KafkaRaftManager$RaftIoThread.doWork(RaftManager.scala:52) > at kafka.utils.ShutdownableThread.run(ShutdownableThread.scala:96) > {code} -- This message was sent by Atlassian Jira (v8.20.10#820010)
