runJobManager方法逻辑比较简单,调用startActorSystemAndJobManagerActors方法中创建ActorSystem和JMActor,然后阻塞等待系统退出,看具体的JM创建过程: defstartActorSystemAndJobManagerActors(configuration:Configuration,executionMode:JobManagerMode,listeningAddress:String,listeningPort:Int,jobManagerClass:Class[_<:JobManager]...
Actor System代表是Flink RPC底层通信(内部是通过Pekko、动态代理、异步编程实现); NetworkManager网络管理,在TaskManager运行Task的时候内部基于Netty封装了一套任务流转的代码,涉及网络管理; Flink 中每条消息都会被放到网络缓冲(network buffer) 中,并以此为最小单位发送到下一个 subtask。 为了维持连续的高吞吐,Flink...

submitJobAndWait方法的第一个参数actorSystem是ActorSystem的实例。在构造Client对象时创建,在Job提交并获得返回结果后通过调用Client的shutdown方法关闭: public
(1) Could not build the program from JAR file 该信息不甚准确,因为绝大多数情况下都不是JAR包本身有毛病,而是在作业提交过程中出现异常退出了。因此需要查看本次提交产生的客户端日志(默认位于$FLINK_HOME/logs目录下),再根据其中的信息定位并解决问题。
