chenshangan commented on KAFKA-2106:
------------------------------------
There are two things here:
1) about 3 replica restriction
I think 3-replica is a conventional way adopted. I've change the restriction
to less or equal than 3 but forget to update the patch. If it's not necessary,
I can remove this restriction. It does not affect the balancing algo.
2) every partition has the same number of replicas
I only make sure every partition of the same topic has the same number of
replicas not all topics. I think it's reasonable. Maybe you misunderstand the
logic ?

> The default partition assignment algorithm can work well in a static kafka
> cluster(number of brokers seldom change). Actually, in production env, number
> of brokers is always increasing according to the business data. When new
> brokers added to the cluster, it's better to provide a tool that can help to
> move existing data to new brokers. Currently, users need to choose topic or
> partitions manually and use the Reassign Partitions Tool
> (kafka-reassign-partitions.sh) to achieve the goal. It's a time-consuming
> task when there's a lot of topics in the cluster.
