But there is an old adage in China called "The Heart of Life", a module of ingenious internal logic (the so-called "heart") whose extension is simple and elegant interface (I call "phase"). Through the definition of the external interface, we can actually harvest

The two most important classes in the Scheduler module are Dagscheduler and TaskScheduler. On the Dagscheduler, this article speaks of TaskScheduler.TaskSchedulerAs mentioned earlier, in the process of sparkcontext initialization, different implementations of TaskScheduler are created based on the type of master. When Master creates Taskschedulerimpl for local, Spark, Mesos, and when Master is YARN, other implementations are created, which the reader

This is a creation in Article, where the information may have evolved or changed. We all know that the go language is native-supported language-level concurrency, and the smallest logical unit of concurrency is Goroutine. Goroutine is a user-state thread provided by the go language, which is, of course, a thread of user-state running on a kernel-level thread. When we create a lot of goroutine, and they are all running on the same kernel thread, we need a sch
