 = 範例一：使用 cat 當 mapper，使用 wc 當 reducer =

 * 用 Standard Alone Mode 跑 hadoop code ( using streaming example )
{{{
hadoop@lucid:~$ cd /opt/hadoop
hadoop@lucid:/opt/hadoop$ bin/hadoop jar ./contrib/streaming/hadoop-0.20.2-streaming.jar -input input -output output -mapper /bin/cat -reducer /usr/bin/wc
}}}

 * 比較：使用 單機安裝模式
{{{
hadoop@lucid:~$ cd /opt/hadoop
// 設定 core-site.xml, hdfs-site.xml, mapred-site.xml
hadoop@lucid:/opt/hadoop$ bin/hadoop namenode -format
hadoop@lucid:/opt/hadoop$ bin/start-all.sh
hadoop@lucid:/opt/hadoop$ bin/hadoop fs -put conf input
hadoop@lucid:/opt/hadoop$ bin/hadoop jar ./contrib/streaming/hadoop-0.20.2-streaming.jar -input input -output output -mapper /bin/cat -reducer /usr/bin/wc
}}}
