使用kafka分区重新分配工具在kafka之后看到"分区不存在"警告/故障

我正在使用kafka 0.8.1.1.我有一个3节点kafka集群,其中一些主题有大约5个分区.我计划在集群中将节点数增加到5,并将现有主题中的一些分区移动到新的代理.

Previous partition state:
broker1 : topic1 { partition 0 }
broker2 : topic1 { partition 1,2}
broker3 : topic1 { partition 3,4}

New intended state:
broker1 : topic1 { partition 0}
broker2 : topic1 { partition 1}
broker3 : topic1 { partition 3}
broker4 : topic1 { partition 4}
broker5 : topic1 { partition 2}

command which I used:
bin/kafka-reassign-partitions.sh --reassignment-json-file partitions-to-move.json --zookeeper zkserver1:2181,zkserver2:2181,zkserver3:2181 --execute

partitions-to-move.json
{
    "partitions":[{"topic": "topic1","partition": 4,"replicas": [4] }],
    "version":1
}

我看到的错误消息:

[2015-12-22 11:19:46,447] WARN [KafkaApi-2] Produce request with correlation id 2462842 from client kafka-node-client on partition [topic1,4] failed due to Partition [topic1,4] doesn't exist on 3 (kafka.server.KafkaApis)

我做了搜索,但找不到任何相关的答案.感谢任何指导/帮助以解决这个问题.
