I have a kafka cluster, every topic in it has only one replica. Recently I extend every topic with 2 replicas. Most topics work fine, but some large topics have some problems with part of partitions. Consumer throw offset OutOfRange exception, the fact is consumer request offset is bigger than the latest offset. I doubt there is some bug with the tool which can add replicas to existing topic.
I add replicas by the following guide: http://kafka.apache.org/081/documentation.html#basic_ops_increase_replication_factor Does anyone face the same problem before and can figure out how to avoid this ? -- have a good day! chenshang'an
