mapreduce算法的phoenix架构实现和一个使用实例，用mapreduce算法对一个输入的文本文件中的单词计数。-mapreduce algorithm phoenix architecture implementation and a use case, use mapreduce algorithm a input text file of the word count.

hadoop的mapreduce初级的几个小案例，包括单词计数、topk、单表关联、多表关联、数据排序、数据去重、数据分组，适合刚接触hadoop的人弄清mapreduce的流程- The primary hadoop mapreduce several small cases, including word count, topk, single-table association, multi-table association, data sorting, data deduplica

hadoop下实现单词的计数，采用分布式形式，使用mapreduce编程框架-Hadoop implementation under the word count, adopting distributed form, the use of graphs programming framework

通过VMware虚拟机搭建ubuntu14.0，采用Linux操作系统、Eclipse工具、 Java语言实现(13/5000 MapReduce word count.)
