我试图增加apachekafka中某个主题的复制因子

kafka-reassign-partitions --zookeeper ${zookeeperid} --reassignment-json-file ${aFile} --execute

最初，我的主题的复制因子是1，有5个分区，我试图将它的复制因子增加到3。当我运行上述命令时，错误是-“有一个现有的分配正在运行”。我的json文件如下所示：

{
    "version": 1,
    "partitions": [
        {
            "topic": "IncreaseReplicationTopic",
            "partition": 0,
            "replicas": [2,4,0]
        },{
            "topic": "IncreaseReplicationTopic",
            "partition": 1,
            "replicas": [3,2,1]
        }, {
            "topic": "IncreaseReplicationTopic",
            "partition": 2,
            "replicas": [4,1,0]
        }, {
            "topic": "IncreaseReplicationTopic",
            "partition": 3,
            "replicas": [0,1,3]
        }, {
            "topic": "IncreaseReplicationTopic",
            "partition": 4,
            "replicas": [1,4,2]
        }
    ]
}

我不知道我哪里出错了。任何提示都将不胜感激。
