本文介绍了 HBase 1.4.0 的安装步骤及配置方法，包括环境变量设置、配置文件调整等，并展示了简单的使用示例。

jia下载地址: http://mirrors.shuosc.org/apache/hbase/1.4.0/

解压 tar -zxvf hbase-1.4.0-bin.tar.gz

修改环境变量

[root@10 hbase-1.4.0]# vi /etc/profile
[root@10 hbase-1.4.0]# source /etc/profile

添加内容:

export HBASE_HOME=/home/sri_udap/app/hbase-1.4.0
export PATH=$PATH:$HBASE_HOME/bin

1. 修改hbase-env.sh文件,添加或修改内容:

export JAVA_HOME=/usr/java/jdk1.8.0_121
export HBASE_CLASSPATH=/home/sri_udap/app/hbase-1.4.0/conf
export HBASE_MANAGES_ZK=true

2.修改hbase-site.xml,添加内容如下:

<configuration>
 #添加如下内容
<property>
    <name>hbase.rootdir</name> #设置hbase数据库存放数据的目录
    <value>hdfs://master:9000/hbase</value>
</property>
<property>
    <name>hbase.cluster.distributed</name>  #打开hbase分布模式
    <value>true</value>
</property>
<property>
    <name>hbase.master</name> #指定hbase集群主控节点
    <value>master:60000</value>
</property>
<property>
    <name>hbase.zookeeper.quorum</name>
    <value>master,slave8,slave9</value> #指定zookeeper集群节点名,因为是由zookeeper表决算法决定的
</property>
<property>
    <name>hbase.zookeeper.property.dataDir</name> #指zookeeper集群data目录
    <value>/home/sri_udap/app/hbase-1.4.0/temp/zookeeper</value>
</property>
</configuration>

修改 regionservers内容为:

[root@master conf]# cat regionservers 
slave8
slave9

将内容拷贝到其他主机,然后bin目录下启动:

./start-hbase.sh

浏览器输入http://10.1.4.58:16030/rs-status查看一下状态:

简单使用下,,如下:

[root@master conf]# hbase shell
