我正在使用本教程来设置第一个 hadoop 项目:
http://hadoop.apache.org/docs/r0.18.3/mapred_tutorial.html#Source+Code
我对这部分感到困惑:
Sample text-files as input:
$ bin/hadoop dfs -ls /usr/joe/wordcount/input/
/usr/joe/wordcount/input/file01
/usr/joe/wordcount/input/file02
$ bin/hadoop dfs -cat /usr/joe/wordcount/input/file01
Hello World Bye World
$ bin/hadoop dfs -cat /usr/joe/wordcount/input/file02
Hello Hadoop Goodbye Hadoop
如何创建文件 file01 和 file02 ?
当我运行上面的命令 () 时,我收到错误:“文件不存在 /usr/joe/wordcount/input/file01”
