>             Project: Kafka
>          Issue Type: Bug
>          Components: clients, offset manager

> For an unknown reason, [kafka data root]/replication-offset-checkpoint was corrupted. First Kafka reported an NumberFormatException in kafka sever.out. And then it reported "error when handling request Name: FetchRequest; ... " ERRORs repeatedly (ERROR details below). As a result, clients cannot read from or write to Kafka on several partitions until replication-offset-checkpoint was manually deleted.
