HBase

一、安装

规划

Node Name	Master	ZooKeeper	RegionServer
node01	yes	yes	no
node02	backup	yes	yes
node03	no	yes	yes

1.1 前置依赖

安装Zookeeper 传送门
安装Hadoop 传送门

1.2 安装Hbase

下载解压

访问Hbase官方，下载最新的bin安装包

[root@node01 opt]# wget https://dlcdn.apache.org/hbase/2.5.5/hbase-2.5.5-bin.tar.gz
[root@node01 opt]# tar -xzf hbase-2.5.5-bin.tar.gz

配置环境变量

[root@node01 opt]# vim /etc/profile.d/my_env.sh
#Hbase
export HBASE_HOME=/opt/hbase
export PATH=$PATH:$HBASE_HOME/bin

分发配置

[root@node01 opt]# xsync /etc/profile.d/my_env.sh

修改hbase-env.sh文件

[root@node01 opt]# vim /opt/hbase/conf/hbase-env.sh
# Tell HBase whether it should manage it's own instance of ZooKeeper or not.
export HBASE_MANAGES_ZK=false

修改hbase-site.xml文件

[root@node01 opt]# vim /opt/hbase/conf/hbase-site.xml

    <property>
        <name>hbase.rootdir</name>
        <value>hdfs://node01:8020/HBase</value>
    </property>
    <property>
        <name>hbase.cluster.distributed</name>
        <value>true</value>
    </property>
    <property>
        <name>hbase.zookeeper.quorum</name>
        <value>node01,node02,node03</value>
    </property>

修改regionservers文件

[root@node01 opt]# vim /opt/hbase/conf/regionservers

node01
node02
node03

修改backup-masters文件

[hadoop@node01 opt]$ vim /opt/hbase/conf/backup-masters

node02
node03

同步分发到其他机器

[root@node01 opt]# xsync hbase

单独配置

node01

修改conf/regionservers,把node01去掉，因为它master不跑RegionServers

HBase启动异常object is not an instance of declaring class 错误

因为和hadoop 包冲突，需要开启以下配置

vim /opt/hbase/conf/hbase-env.sh

# Tell HBase whether it should include Hadoop's lib when start up,
# the default value is false,means that includes Hadoop's lib.
export HBASE_DISABLE_HADOOP_CLASSPATH_LOOKUP="true"

单点启动

[root@master01 opt]# hbase-daemon.sh start master
[root@master01 opt]# hbase-daemon.sh start regionserver

群启hbase

[root@node01 opt]# /opt/hbase/bin/start-hbase.sh

检查

# jps查看
[root@node01 hbase]# xcall jps

37907 HMaster
38231 HRegionServer
=============== slave01 ===============
49774 HRegionServer

二、使用(shell)

查看表

hbase:001:0> scan 'user_info'

创建表

create 'employee','company','family'

put 'employee','row1','company:name','ted'
put 'employee','row1','company:position','worker'
put 'employee','row1','family:tel','13600912345'

put 'employee','row2','company:name','michael'
put 'employee','row2','company:position','manager'
put 'employee','row2','family:tel','1234912341324'

scan 'employee'

创建表空间

-- 查看表空间
