Xue Liu updated KAFKA-9207: --------------------------- Description: We sometimes see a replica for a partition is out of sync. When the issue happens, it seems that we just lost that replica (would never catch-up), unless we restart that broker. It appears that ReplicaFetcher thread for that partition is dead. We didn't see any exception in server or controller logs. was: We sometimes see a replica for a partition is out of sync.
