Python" (see references), Spark founder John Aycock divides the compiler into four phases. The problems discussed in this article only involve the first two half-stages, which are attributed to two reasons: first, due to the length constraints of the article, second, we will only discuss the relatively simple "text Mark" mentioned in the previous article. Spark can also be further used as a full-cycle code compiler/interpreter, rather than just for the "parse and process" task I described. Let'

Two download Methods: If git is installed, go to the git console and use the following commandGit clone git: // github.com/mishoo/UglifyJS.gitOr use http to download the file and click zip to download the file. After decompression, the directory structure is as follows: 2. Create a project (folder) myApp and copy the uglify-js.js and lib directories to yo

issues discussed in this article relate only to the previous two-and-a-half stages, due to two reasons, one because of the length of the article, and the other because we will only discuss the same relatively simple "text tag" problem presented in the previous article. Spark can also be used further as a code compiler/interpreter for the full cycle, not just for the "parse and process" task I described. Let's take a look at the four stages of Aycock (abbreviated by reference): Scanning,

rows of data, then the same field will be sorted separately, only need to record lastkey in the reduce phase can be heavy. This implementation is a good use of the mapreduce sequencing, saving the reduce phase deduplication memory consumption, but the disadvantage is to increase the amount of shuffle data. It is important to note that when you generate reduce value, the value of the remaining distinct data rows can be empty except for the row in which the first distinct field is left. 2. The pr

The process of converting SQL to MapReduceAfter learning about the basic SQL operations of MapReduce, let's look at how hive transforms SQL into a MapReduce task, and the entire compilation process is divided into six phases: ANTLR defines SQL syntax rules, completes SQL lexical, parses syntax, transforms SQL into abstract syntax trees ast tree Iterate through the AST Tree and abstract out t

say, this has to know the compiler, right, is the compiler, but also not so complex, also used a little bit AST knowledge, do not know AST? Oh, there's nothing wrong with Eclipse doing it for you.So I started to implement such a quick fix in the Java source code in the license declaration of the gadget, the basic idea is based on the Eclipse JDT in the AST imple
