结合理论和实践,<Hadoop权威指南第四版>由浅入深,全方位介绍了Hadoop 这一高性能的海量数据处理和分析平台.5部分24 章,第Ⅰ部分介绍Hadoop 基础知识,第Ⅱ部分介绍MapReduce,第Ⅲ部分介绍Hadoop 的运维,第Ⅳ部分介绍Hadoop 相关开源项目,第Ⅴ部分提供了三个案例. Hadoop生态都有涉及,很厚很全:HDFS, MapReduce1&2(YARN), Hive, HBase, Pig, ZooKeeper, Sqoop等. 多数章节对自己的要求都是了

前期已经完成了hadoop全分布模式的部署和运行,近期想更进一步的了解hadoop原理,基于hadoop2.X的书籍最好的莫过于<hadoop权威指南(第四版)>,很可惜作者年初才刚写完,没来得及翻译,只好看英文版了,书中的要点重点在接下来的一段时间我会依次翻译出来(全部翻译不太现实,没那么多时间精力,将近900页呢),如果有翻译不妥的地方,还请大家指出来,共同进步,谢谢! 今天是个开头,就先翻译一下文中前言和序的要点 1.Foreword 1) Wesplit off the distrib

敲了一下hadoop权威指南第二章的例题,虽然基本上是照着书上敲的,但还是把它放到这方便以后查看. 代码如下: <span style="font-size:18px;"><span style="font-size:18px;">import java.io.IOException; import java.util.StringTokenizer; import org.apache.hadoop.conf.Configuration;

a) The trend is for every individual's data footprint to grow, but perhaps more significantly,the amount of data generated by machines as a part of the Internet of Things will be even greater than that generated by people. 每个人在互联网上的足迹数据(或者说痕迹)会一直增长,但

Filesystems that manage the storage across a network of machines are called distributed filesystems. Since they are network based, all the complications of network programming kick in, thus making distributed filesystems more complex than regular dis

5) The Java Interface a) Reading Data from a Hadoop URL. 使用hadoop URL来读取数据 b) Although we focus mainly on the HDFS implementation, DistributedFileSystem, in general you should strive to write your code against the FileSystem abstract class, to retain

Most importantly, MapReduce programs are inherently parallel, thus putting very large-scale data analysis into the hands of anyone with enough machines at their disposal.MapReduce comes into its own for large datasets, so let's start by looking at on

hadoop版本1.2.1 jdk1.7.0 例3-1.通过URLStreamHandler实例以标准输出方式显示Hadoop文件系统的文件 hadoop fs -mkdir input 在本地创建两个文件file1,file2,file1的内容为hello world,file2内容为hello Hadoop,然后上传到input,具体方法如Hadoop集群(第6期)_WordCount运行详解中 2.1.准备工作可以看到. 完整代码如下: 1 import org.apache.hadoop
