Hi, My kafka cluster has a __consumer_offsets topic with 50 partitions (the default for offsets.topic.num.partitions) but with a replication factor of just 1 (the default for offsets.topic.replication.factor should be 3).
From the docs http://kafka.apache.org/documentation.html: offsets.topic.replication.factor 3 The replication factor for the offset commit topic. A higher setting (e.g., three or four) is recommended in order to ensure higher availability. If the offsets topic is created when fewer brokers than the replication factor then the offsets topic will be created with fewer replicas. I'm guessing there's a typo there? I'm guessing it should be: If the offsets topic is created when fewer brokers than the replication factor [are active], then the offsets topic will be created with fewer replicas. Or something along those lines? Thanks, -James
