Kamal Chandraprakash 93adaea599 KAFKA-19523: Gracefully handle error while building remoteLogAuxState (#20201) ... Improve the error handling while building the remote-log-auxiliary state when a follower node with an empty disk begin to synchronise with the leader. If the topic has remote storage enabled, then the ReplicaFetcherThread attempt to build the remote-log-auxiliary state. Note that the remote-log-auxiliary state gets invoked only when the leader-log-start-offset is non-zero and leader-log-start-offset is not equal to leader-local-log-start-offset. When the LeaderAndISR request is received, then the ReplicaManager#becomeLeaderOrFollower invokes 'makeFollowers' initially, followed by the RemoteLogManager#onLeadershipChange call. As a result, when ReplicaFetcherThread initiates the RemoteLogManager#fetchRemoteLogSegmentMetadata, the partition may not have been initialized at that time and throws retriable exception. Introduced RetriableRemoteStorageException to gracefully handle the error. After the patch: ``` [2025-07-19 19:28:20,934] INFO [ReplicaFetcher replicaId=3, leaderId=1, fetcherId=0] Could not build remote log auxiliary state for orange-1 due to error: RemoteLogManager is not ready for partition: orange-1 (kafka.server.ReplicaFetcherThread) [2025-07-19 19:28:20,934] INFO [ReplicaFetcher replicaId=3, leaderId=2, fetcherId=0] Could not build remote log auxiliary state for orange-0 due to error: RemoteLogManager is not ready for partition: orange-0 (kafka.server.ReplicaFetcherThread) ``` Reviewers: Luke Chen <showuon@gmail.com>, Satish Duggana <satishd@apache.org>		2025-07-23 19:29:31 +05:30
