Hadoop入门学习之二：一步一步运行WordCont
WordCount是学习Hadoop的经典入门范例。下面通过一步步的操作，来编译、打包、运行WordCount程序。
1、在Hadoop 1.0.4的解压目录的如下位置可以找到WordCount.java的源文件
src/examples/org/apache/hadoop/examples/WordCount.java
2、新建一个dev的文件夹，将WordCount.java拷贝至dev/wordcount文件夹下
ubuntu@ubuntu:~$ hadoop fs -ls /tmp/output/resultFound 3 items-rw-r--r-- 1 ubuntu supergroup 0 2013-01-24 08:10 /tmp/output/result/_SUCCESSdrwxr-xr-x - ubuntu supergroup 0 2013-01-24 08:09 /tmp/output/result/_logs-rw-r--r-- 1 ubuntu supergroup 96 2013-01-24 08:10 /tmp/output/result/part-r-00000ubuntu@ubuntu:~$ hadoop fs -cat /tmp/output/result/part-r-00000a 2am 2are 2brother 1he 1how 2i 2is 3lily 1lily. 1my 2name 1she 1student! 2you? 2ubuntu@ubuntu:~$
