------------------------------------------
Agree, but since I've been working on the previous issue KAFKA-1782 that is
already closed - I've made few minor changes here.
> Changing replication factor
> ---------------------------
>
> Key: KAFKA-1543
> URL: https://issues.apache.org/jira/browse/KAFKA-1543
> Project: Kafka
> Issue Type: Improvement
> Reporter: Alexey Ozeritskiy

>
> It is difficult to change replication factor by manual editing json config.
> I propose to add a key to kafka-reassign-partitions.sh command to
> automatically create json config.
> Example of usage
> {code}
> kafka-reassign-partitions.sh --zookeeper zk --replicas new-replication-factor
> --topics-to-move-json-file topics-file --broker-list 1,2,3,4 --generate >
> output
> {code}
