Kafka ReassignPartitionsCommand：IllegalArgumentException：long 不是值类型

Question

我正在尝试在我的项目中重新分配分区，但出现此错误。

    2017-08-22 15:57:28 DEBUG ZookeeperBackedAdoptionLogicImpl:320 - Calling ReassignPartitionsCommand with args:[--reassignment-json-file=partitions-to-move.json.1503417447767, --zookeeper=172.31.14.207:2181, --execute]

我创建 json 文件并将其用作重新分配分区的输入。我尝试将相同的文件与 kafka 的内置脚本一起使用，它正在工作。

kafka-reassign-partitions.bat --reassignment-json-file=partitions-to-move.json.1503417447767 --zookeeper=172.31.14.207:2181 --execute

我还尝试使用相同的代码编写一个简单的程序来测试相同的文件，它也能正常工作。任何 json 文件都会发生这种情况，我在测试之前重置了 kafka 环境。

public class reassignPartition {
private static CuratorFramework client;
public static void main (String[] args) {
    client = CuratorFrameworkFactory.newClient(args[0] + ":2181", new ExponentialBackoffRetry(1000, 30));
    client.start();
    String reassignmentConfigFileName = args[1];
    String[] reassignCmdArgs = { "--reassignment-json-file=" + Paths.get(reassignmentConfigFileName),
            "--zookeeper=" + client.getZookeeperClient().getCurrentConnectionString(), "--execute" };
    System.out.println("Calling ReassignPartitionsCommand with args:{}"+ Arrays.toString(reassignCmdArgs));
    ReassignPartitionsCommand.main(reassignCmdArgs);
}
}

可能是什么问题？

更新：Json 内容

{"partitions":[{"topic":"test1","partition":0,"replicas":[1]}],"version":1}

这是版本不匹配。使用不同版本的陷阱之一。 Kafka 0.10.2.0 使用 jopt-simple-4.9.jar，Kafka 0.11.0.0 使用 jopt-simple-5.0.4.jar
