搭建Hadoop运行环境

Experiments:

Example 1: use FsShell to list the files in  the root of Hadoop Distributed File System:

Example 2: use FsShell to transfer the file from Linux File System to Hadoop Distributed File System:

Note: hadoop fs –mkdir inputDir  ->(在Hadoop分布式文件系统中创建一个叫inputDir的目录)

           ls –al ~/tmp  -> (查看Linux本地文件系统中~/tmp目录下是否有一个文件叫 canton_codetemplates.xml)

           hadoop fs –put ~/tmp/*.xml inputDir –>（让Hadoop FsShell 将上述文件从Linux本地文件系统转移到Hadoop分布式文件系统的inputDir 目录）

           hadoop fs –ls inputDir  -> (让Hadoop FsShell检查是否成功转移，即在inputDir目录中是否已经有目标文件)
