非Cygwin、非虚拟机

  开始接触Hadoop,听人说一般都是在Lunix下部署Hadoop,但是本人Lunix不是很了解,所以Google以下如何在Win10下安装Hadoop(之后再在Lunix下弄),找到不少文章,以下是主要参考的文章:

  1、Hadoop installation on windows without cygwin in 10 mints

  2、Win10系统安装Hadoop与Hbase

  3、Apache Hadoop for Windows Platform

  这里是按照第一篇文章操作的。

  一、安装jdk,,地址为  具体的操作以及配置环境变量这里就不演示了,这里有一点需要注意的是默认会安装在C:\Program Files 下,开始我也是安装在这里,但是后来报错了,报什么“JAVA_HOME”的错误具体的记不清了。查了一下说是因为安装路径中有空格,晕了,所以安装在如下目录:

  二、下载Hadoop,地址为 https://mirrors.tuna.tsinghua.edu.cn/apache/hadoop/common/stable/  这里选择的是hadoop-2.7.3.tar.gz

  三、将其解压到某一文件夹,这里为D:\hadoop\hadoop-2.7.3

  四、添加“HADOOP_HOME”环境变量,并添加到Path环境变量中,按照下图操作

  五、修改Hadoop配置文件,在这之前你要先下载sardetushar_gitrepo_download ,之后解压,删掉D:\hadoop\hadoop-2.7.3目录下的bin、etc文件夹,用刚刚解压的替换。

  1、D:\hadoop\hadoop-2.7.3\etc\hadoop\core-site.xml

  3、D:\hadoop\hadoop-2.7.3\etc\hadoop\hdfs-site.xml

  这个配置这里要感谢一下这篇帖子:  按照第一篇教程配置会出错的!!!

<configuration> <property> <name>dfs.replication</name> <value>1</value> </property> <property> <name>dfs.namenode.name.dir</name> <value>hadoop/data/namenode</value> </property> <property> <name>dfs.datanode.data.dir</name> <value>hadoop/data/datanode</value> </property> </configuration>
