安装步骤如下：
1：安装了ssh [windows版本的]
2: 安装了JDK[windows版本的]
/cygdrive/d/JAVA/jdk1.7.0/
3:下载hadoop-1.0.2.tar.gz
解压在目录d:/hadoop/下
4:进入hadoop-1.0.4
编辑conf如下配置文件
A: hadoop-evn.sh
将原来的#export JAVA_HOME=...替换为
export JAVA_HOME=/cygdrive/d/JAVA/jdk1.7.0/
注意和后面的#隔一个空格
B:core-site.xml
配置如下
fs.default.name
hdfs://localhost:9000
hadoop.tmp.dir
/hadoop/temp
C:hdfs-site.xml
首先创建hadoop的hdfs的name和data目录
mkdir /hadoop/hsdf/name
mkdir /hadoop/hsdf/data
也可以手动在相应文件夹下创建目录
dfs.name.dir
/hadoop/hdfs/name
dfs.data.dir
/hadoop/hdfs/data
dfs.replication
1
D: mapred-site.xml
首先创建hadoop的mapred的local和system目录
mkdir /hadoop/mapred/local
mkdir /hadoop/mapred/system
也可以手动在相应文件夹下创建目录
mapred.job.tracker
localhost:9001
mapred.local.dir
/hadoop/mapred/local
mapred.system.dir
/hadoop/mapred/system
E:配置masters和slaves文件
localhost
原文件已有可不修改
6:格式化namenode
先到hadoop当前目录下
$
cd d:/hadoop
再进行格式化
$ bin/hadoop namenode -format

7:启动
启动hadoop
$ bin/start-all.sh
starting namenode, logging to
/cygdrive/d/hadoop/libexec/../logs/hadoop-dy-namenode-dy-PC.out
localhost: starting datanode, logging to
/cygdrive/d/hadoop/libexec/../logs/hadoop-dy-datanode-dy-PC.out

现在可以登录
localhost:50030
localhost:50070
查看是否配置成功
8:关闭
关闭hadoop
$ bin/stop-all.sh
