我有一个kafka代理，正在使用kafka节点在nodejs中实现kafka。我想用3个分区创建一个主题。执行此操作时，出现的问题是，只有第一个分区得到了leader assign，而其他两个分区没有得到leader。我要为所有分区指定引线。谁能告诉我怎么做？提前谢谢。

var client = new kafka.KafkaClient();
    var topic = 't-26';
    var topicsToCreate = [
        {
            topic: topic,
            partitions: 3,
            Leader: 0,
            replicationFactor: 1,
            replicaAssignment: [
            {
              partition: 0,
              replicas: [0]
            },
            {
                partition: 1,
                replicas: [1]
            },
            {
                partition: 2,
                replicas: [2]
            }
          ]
        },
        ];
        client.createTopics(topicsToCreate, (error, result) => {
             console.log(result);
        });

主题创建如下-

Topic: t-26     PartitionCount: 3       ReplicationFactor: 1    Configs:
        Topic: t-26     Partition: 0    Leader: 0       Replicas: 0     Isr: 0
        Topic: t-26     Partition: 1    Leader: none    Replicas: 1     Isr:
        Topic: t-26     Partition: 2    Leader: none    Replicas: 2     Isr:
