HazelcastSerializationException：当 Jet 作业在多个集群上 运行
HazelcastSerializationException: When Jet job is running over multiple cluster
我正在尝试 运行 Hazelcast-jet 之一 example 通过分布式系统。我的 objective 是 运行 在分布式系统上编码，利用多台机器的处理能力。我有两台笔记本电脑通过局域网连接。当我 运行 这个例子在一台机器上工作正常时，运行 这两个系统我只用 jet 实例启动机器 1 和机器 2。两台机器上的代码都是，

任何人都可以帮我解决我做错了什么吗？
您需要将class添加到JobConfig并在提交管道时传递它：
JobConfig jobConfig = new JobConfig();
jobConfig.addClass(PrimeFinder.class);
jet.newJob(dag, jobConfig).join();

您需要将class添加到JobConfig并在提交管道时传递它：
JobConfig jobConfig = new JobConfig();
jobConfig.addClass(PrimeFinder.class);
jet.newJob(dag, jobConfig).join();
