11 free IDE editors are released!GuideJava developers need to spend a lot of time in Java code and use different IDES (Intergrated Development Environment) to develop Java code, so next I will introduce 11 different ides, which provide a variety of functions, such: build Java applications, TestNG, debugging, code check, Code help, JUNIT testing, multivariate refactoring, visual GUI builder and code editor, Java and Maven build tools, ant, Data Modelin

工欲善其事, its prerequisite. Each IDE has its own advantages, the right is the best."Bole Online" Python is very easy to learn and powerful programming language. Python includes an efficient and advanced data structure that provides simple and efficient object-oriented programming. The learning process for Python involves either an IDE or a code editor, or an integrated development editor (

"A real programmer does not use the IDE (the Integration development environment), they write code with a text editor with a certain plug-in." "We can always hear such views in some places. However, although more and more people agree with this view, an IDE is still very useful, it is easy to set up and easy to use, so it is no more appropriate to write a project than this. So in view of this, I would like

This document is from my Evernote, when I am still at Baidu, I had a complete Hadoop development/debug environment. But at that time, I was tired of writing blogs. It costs me day's spare time to recovery from where I was stoped. Hope The blogs would keep on. Still cherish the time speed there, cause if doing the same thing at both different time and different place, t He things is still there, but mens is no more than the same one. Talk too much, let

下午对着源码看陆喜恒. Hadoop实战（第2版）6.4.1 （Shuffle和排序）Map端，发现与Hadoop 1.2.1的源码有些出入。下面作个简单的记录，方便起见，引用自书本的语句都用斜体表示。 依书本，从MapTask.java开始。这个类有多个内部类： 从书的描述可知，collect()并不在MapTask类，而在MapOutputBuffer类，其函数功能是 1、定义输出内存缓冲区为环形结构2、定义输出内存缓冲区内容到磁盘的操作 在collect函数中将缓冲区的内容写出时会调用sortAndSpill函数。好了，从这里开始就开始糊涂了，因为collect()没调用这个函数，接触Hadoop也就几天时间，啥都不懂，一下晕了。 简单表示下当前的函数调用关系： 0 ----MapOutputBuffer::co
