Hadoop1.1.2

创建两个文本

cd /home/duxiaoming
mkdir input
cd input/
echo "hello world" > test1.txt
echo "hello hadoop" > test2.txt

拷贝到Hadoop文件系统

cd hadoop-1.1.2
bin/hadoop fs -put ../input ./in                 // ./ 默认代表/user/duxiaoming/
bin/hadoop fs -ls ./in/*             //查看详情

运行jar包

bin/hadoop jar hadoop-examples-1.1.2.jar wordcount in out         //分析in目录下的文件，输出到out目录

查看生成的文件

/user/duxiaoming/out/_SUCCESS
/user/duxiaoming/out/_logs
/user/duxiaoming/out/part-r-0000

bin/hadoop fs -cat ./out/part-r-0000
