64位ubuntu下单节点安裝配置hadoop2.5.0
1、在Ubuntu下创建hadoop用户组和用户
2、在Ubuntu下安装JDK(可以在官网下载linux包然后解压安装)
3、hadoop下载:http://www.apache.org/dyn/closer.cgi/hadoop/common/
因为64位ubuntu需要编译源文件:故下载hadoop-2.5.0-src.tar.gz
(1)编译时需要安装protobuf-2.5.0,解压下载的protobuf-2.5.0.tar.gz
,进入protobuf-2.5.0目录,执行下面命令
./configure --prefix=/usr
sudo make
sudo make check
sudo make install
验证:protoc --version
(2)安装Maven。
(3)编译hadoop
解压hadoop-2.5.0-src.tar.gz,进入hadoop-2.5.0-src,执行下面命令
mvn package -Pdist,native -DskipTests -Dtar

编译好的文件在hadoop-dist/target中
4、安装配置

安装完跑一下:jar share/hadoop/mapreduce/hadoop-mapreduce-examples-2.5.0.jar grep input output ‘dfs[a-z.]+‘
