Thanks so much for your reply, Erick Erickson. We want to increase replicationFactor from 1 to 2 to, but I am wondering what's the advantage to do so. Whether this will make our system more robust and resilient to temporary network failure issue?
Say if we have 3 machines, and split data into 3 shards, if we set replicationFactor to 2, machine A contains data from shard 1. shard2, machine B contains shard2, shard 3, machine c contains shard3, shard 1 If machine A is down or has temporally network issue, whether the system can continue work? -- I would guess so, as you suggested, the zookeeper is used to maintain cluster info, then zookeeper will figure out and choose new leader if needed and the system will keep running.
