Subject [jira] [Created] (KAFKA-1543) Changing replication factor
Date Thu, 17 Jul 2014 13:05:04 GMT
Alexey Ozeritskiy created KAFKA-1543:

             Summary: Changing replication factor
                 Key: KAFKA-1543
                 URL: https://issues.apache.org/jira/browse/KAFKA-1543
             Project: Kafka
          Issue Type: Improvement
            Reporter: Alexey Ozeritskiy
         Attachments: can-change-replication.patch

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

Example of usage
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
