Neha Narkhede updated KAFKA-821:
--------------------------------
Labels: kafka-0.8 p1 (was: )
> specifying a non-existent partition to ./bin/kafka-reassign-partitions.sh
> breaks all reassignment ops
> -----------------------------------------------------------------------------------------------------
>
> Key: KAFKA-821
> URL: https://issues.apache.org/jira/browse/KAFKA-821
> Project: Kafka
> Issue Type: Bug
> Components: tools
> Affects Versions: 0.8
> Reporter: Scott Clasen
> Assignee: Neha Narkhede
> Labels: kafka-0.8, p1
>
> From my ML post...the workaround is to manually delete
> /admin/reassign_partitions from ZK, that node contained a json with an empty
> partitions array.
> Have 3 brokers running. Ids 25,26,27
> ./bin/kafka-create-topic.sh --replica 3 --topic first-cluster-topic
> --zookeeper <zk>:2181/kafka
> Seems fine, can send/receive, etc..
> Kill 27, start 28. Try to reassign the single partition topic with the
> following json.
> Contains an error. partition should be 0 not 1.
> {"partitions":
> [{"topic": "first-cluster-topic", "partition": 1, "replicas": [25,26,28] }]
> }
> ./bin/kafka-reassign-partitions.sh --zookeeper ... -path-to-json-file
