Alexis Lesieur commented on KAFKA-1313: --------------------------------------- I feel like an "easy" fix for this would at least be enable the {code}bin/kafka-reassign-partitions.sh --generate --topics-to-move-json-file{code} to take an optional parameter for each topic that would be rf. That way, at least, we would have an easy way to generate assignments with higher rf. > Support adding replicas to existing topic partitions via kafka-topics tool > without manually setting broker assignments > ---------------------------------------------------------------------------------------------------------------------- > > Key: KAFKA-1313 > URL: https://issues.apache.org/jira/browse/KAFKA-1313 > Project: Kafka > Issue Type: New Feature > Components: tools > Affects Versions: 0.8.0 > Reporter: Marc Labbe > Assignee: Sreepathi Prasanna > Labels: newbie++ > > There is currently no easy way to add replicas to an existing topic > partitions. > For example, topic create-test has been created with ReplicationFactor=1: > Topic:create-test PartitionCount:3 ReplicationFactor:1 Configs: > Topic: create-test Partition: 0 Leader: 1 Replicas: 1 Isr: 1 > Topic: create-test Partition: 1 Leader: 2 Replicas: 2 Isr: 2 > Topic: create-test Partition: 2 Leader: 3 Replicas: 3 Isr: 3 > I would like to increase the ReplicationFactor=2 (or more) so it shows up > like this instead. > Topic:create-test PartitionCount:3 ReplicationFactor:2 Configs: > Topic: create-test Partition: 0 Leader: 1 Replicas: 1,2 Isr: 1,2 > Topic: create-test Partition: 1 Leader: 2 Replicas: 2,3 Isr: 2,3 > Topic: create-test Partition: 2 Leader: 3 Replicas: 3,1 Isr: 3,1 > Use cases for this: > - adding brokers and thus increase fault tolerance > - fixing human errors for topics created with wrong values -- This message was sent by Atlassian JIRA (v6.3.15#6346)
