1. 什么是Task? 在前面的章节里描写叙述过几个角色,Driver(Client),Master,Worker(Executor),Driver会提交Application到Master进行Worker上的Executor上的调度,显然这些都不是Task. Spark上的几个关系能够这样理解: Application: Application是Driver在构建SparkContent的上下文的时候创建的,就像申报员,如今要构建一个能完毕任务的集群,须要申报的是这次须要多少个Executor…

Task.Waitall阻塞了当前线程直到全完.whenall开启个新监控线程去判读括号里的所有线程执行情况并立即返回,等都完成了就退出监控线程并返回监控数据. task.Result会等待异步方法返回,当然阻塞住了.别和await 同时用. Task和ThreadPool的功能类似,可以用来创建一些轻量级的并行任务.对于将一个任务放进线程池    ThreadPool.QueueUserWorkItem(A); 这段代码用Task来实现的话,方式如下:    Task.Factory.Star…
