基于伪分布式Hadoop集群搭建伪分布式HBASE集群

---

前言

本文目的在于基于伪分布式Hadoop集群搭建伪分布式HBASE集群，搭建伪分布式Hadoop集群环境教程为基于百度智能云服务器搭建伪分布式Hadoop集群

运行环境

1、CentOS / 7.9 x86_64 (64bit)

2、jdk-8u281-linux-x64

3、hadoop-2.7.6

4、hbase-2.2.0

解压HBASE

cd /software/
tar -zxvf /download/hbase-2.2.0-bin.tar.gz
mv hbase-2.2.0/ hbase

配置HBASE

配置系统变量

vi /etc/profile

按文件末尾按insert，输入以下内容

#hbase
export HBASE_HOME=/software/hbase
export PATH=$HBASE_HOME/bin:$PATH

按esc输入：wd按回车

检验结果

hbase version

如果成功结果如下

配置hbase-env.sh文件

cd hbase/conf/
vi hbase-env.sh

export JAVA_HOME=/software/jdk
export HBASE_CLASSPATH=/software/hbase/conf
export HBASE_MANAGES_ZK=true

按esc输入：wd按回车

配置hbase-site.xml

cd hbase/conf/
vi hbase-site.xml

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>

     <value>/software/data/tmp/zookeeper-hbase</value>
 </property>
</configuration>

按esc输入：wd按回车

mkdir -p /software/data/tmp/zookeeper-hbase

配置regionservers文件

vi regionservers

修改文件内容为：

localhost 

启动集群

启动HBASE前需先启动Hadoop，可用jps检查

如图所示即可进行下一步

cd /software/hbase/bin/
./start-hbase.sh

如图所示即为启动成功

如成功即为如图所示

HBASE集群初体验

启动客户端

hbase shell

查看现有表

list

结果如下：

创建一张表tb，表中含有一个列簇mycf

create 'tb','mycf'  

检查结果

list

结果如下：
