我在构建我的snappy. 我按照以下步骤操作：
- 从http://code.google.com/p/snappy/下载。
- 用命令解压它
tar xvzf snappy-1.1.3 - 然后按照以下命令
hadoop@HadoopPseudoVM:~$ mv google-snappy-0852af7 snappy1 hadoop@HadoopPseudoVM:~$ vi /home/hadoop/.bashrc
hadoop@HadoopPseudoVM:~$ exec bash
hadoop@HadoopPseudoVM:~$ mvn package -Dsnappy.prefix=/home /hadoop/snappy1
