Preface:
Spark has been very popular recently. This article does not talk about spark principles, but studies how to compile spark cluster construction and service scripts. We hope to understand spark clusters from the perspective of running scripts.
Recently saw a post on the spark architecture, the author is Alexey Grishchenko. The students who have seen Alexey blog should know that he understands spark very deeply, read his "spark-architecture" this blog, a kind of clairvoyant feeling, from the JVM memory allocation to the Spark cluster resource management, step

1. Optimization? Why? How? When? What?
"Spark applications also need to be optimized. "Many people may have this question," not already have code generators, executive optimizer, pipeline or something. ”。 Yes, Spark does have some powerful built-in tools to make your code faster when it executes. But if everything depends on the tools, framework to do, I think that can only illustrate two questions: you a
