基于Hadoop完全分布式安装的基础上

创建测试文件

mkdir file
cd file/
echo "Hello word" > file1.txt
echo "Hello a word" > file2.txt

创建HDFS目录

cd ~/hadoop/
sbin/start-all.sh
bin/hadoop fs -mkdir /input2

上传测试文本

cd ~/file
../hadoop/bin/hadoop fs -put file* /input2/
../hadoop/bin/hadoop fs -ls /input2/

执行WordCount

cd ~/hadoop
bin/hadoop jar share/hadoop/mapreduce/hadoop-mareduce-examples-3.2.2.jar wordcount /input2 /output2/wordcount1

bin/hadoop fs -cat /output2/wordcount1
