Windows10环境下安装Hbase单机版

题记：


拉勾JAVA高薪训练营

1.下载安装包

hadoop官网地址：https://hadoop.apache.org/releases.html

hbase官网地址：http://archive.apache.org/dist/hbase

2.配置hadoop环境

在系统环境变量中增加HADOOP_HOME,并在path中增加%HADOOP_HOME%\bin

3.配置hbase环境

在hbase-1.2.10\conf下找到hbase-env.cmd

配置以下属性：

set HBASE_MANAGES_ZK=false
set JAVA_HOME=D:\DEV\env\jdk1.8.0_77

set HBASE_CLASSPATH=F:\hbase\hbase-1.2.10\conf

JAVA_HOME配置自己的jdk路径

HBASE_CLASSPATH配置自己的hbase中conf文件夹路径

在hbase-1.2.10\conf中找到hbase-site.xml

配置以下属性：

<configuration>
    <property>  
        <name>hbase.rootdir</name>  
        <value>file:///F:/hbase/hbase-1.2.10/root</value>  
    </property>  
    <property>  
        <name>hbase.tmp.dir</name>  
        <value>F:/hbase/hbase-1.2.10/tem</value>  
    </property>  
    <property>  
        <name>hbase.zookeeper.quorum</name>  
        <value>127.0.0.1</value>  
    </property>  
    <property>  
        <name>hbase.zookeeper.property.dataDir</name>  
        <value>F:/hbase/hbase-1.2.10/zoo</value>  
    </property>  
    <property>  
        <name>hbase.cluster.distributed</name>  
        <value>false</value>  
    </property>  
</configuration>

同样，涉及到路径的都配置自己的hbase中的路径，其中没有的文件夹，会自己创建

4.启动hbase

进入到hbase-1.2.10\bin目录下，启动start-hbase.cmd，看到控制台无报错信息，并启动停止即可

在cmd模式下，进入到hbase-1.2.10\bin目录下：

输入命令：hbase shell

出现hbase（main）:001.0>

恭喜，成功搭建好单机版的hbase环境

5.java连接测试
