Scott Clasen commented on KAFKA-864: ------------------------------------ Yes, agree that is possible, but if you want to do any automation of moving partitions, rotating servers, etc, the output format of ./bin/kafka-list-topic.sh makes doing this painful. Cold ./bin/kafka-list-topic.sh be modified to (optionally with --json ?) to output a json format that kafka-reassign-partitions.sh can understand? That would make automating things easier and basically cover the above functionality > bin/kafka-gen-reassignment.sh > ----------------------------- > > Key: KAFKA-864 > URL: https://issues.apache.org/jira/browse/KAFKA-864 > Project: Kafka > Issue Type: Improvement > Affects Versions: 0.8 > Reporter: Scott Clasen > > Better tooling for replacing failed brokers and reassigning partitions. > The output of ./bin/kafka-list-topic.sh makes doing this in bulk painful. > Tool should output json format acceptable to > ./bin/kafka-reassign-partitions.sh > Spec: bin/kafka-gen-reassignment.sh > Option Description > ------ ----------- > --topic <topic> REQUIRED: The topic to be reassigned. > Defaults to all existing topics. > (default: ) > --partition <partition> REQUIRED: The partition to be > reassigned. > Defaults to all partitions. > (default: ) > --from <broker-id> REQUIRED: The broker to reassign the > partition from > --to <broker-id> REQUIRED: The broker to reassign the > partition to. > --zookeeper <urls> REQUIRED: The connection string for > the zookeeper connection in the form > host:port.
