一个自己写的Hadoop MapReduce实例源码，网上看到不少网友在学习MapReduce编程，但是除了wordcount范例外实例比较少，故上传自己的一个。包含完整实例源码，编译配置文件，测试数据，可执行jar文件，执行脚本及操作步骤。学习完此例子后，你能掌握MapReduce基础编程，及如何编译Java文件，打包jar文件，编写shell执行脚本等。后续学习还可以参看本人的CSDN博客，如有问题也可以在线为你解答，不过本人也学习Hadoop不足一年，现学现卖而已，也可能力不能及，有些难的也很有可能不懂。希望能够帮助到学习MapReduce的朋友(A written Hadoop MapReduce example source code line to see a lot of friends in the learning MapReduce programming, but in addition to the wordcount example instance is relatively small, so upload your own. Contains the full example source code, the compiler configuration files, test data, executable jar file, execute the script and steps. Learn this example, you can grasp the the MapReduce basis of programming, and how to compile Java files, packaged jar file, write shell execute the script. Follow-up study can also see my CSDN blog if the problem is also available online for you to answer, but I also learned that for Hadoop less than a year, buying and learning it can also power can not and some difficulty also likely to understand . Want to be able to help to learn MapReduce friend)
