【HBase】安装与使用

下载HBase(注意下载与您使用的hadoop版本兼容的版本)

前提：hadoop HA,zookeeper是正常的。

1.解压

tar -zxvf hbase压缩包 -C 解压后存储路径

2.配置环境变量

vi /etc/profile

export HBASE_HOME=/usr/local/hadoop/hbase-2.0.0
export PATH=$HBASE_HOME/bin:$PATH

source /etc/profile

3.hbase-site.xml

<configuration>
   <property>
       <name>hbase.rootdir</name>
       <value>hdfs://192.168.195.132:9000/hbase</value>
   </property>
       <!--启用分布式集群-->
   <property>
       <name>hbase.cluster.distributed</name>
       <value>true</value>
   </property>
       <!--默认HMaster HTTP访问端口-->
   <property>
       <name>hbase.master.info.port</name>
       <value>16010</value>
    </property>
       <!--默认HRegionServer HTTP访问端口-->
    <property>
       <name>hbase.regionserver.info.port</name>
       <value>16030</value>
    </property>
   <property>
       <name>hbase.zookeeper.quorum</name>
       <value>192.168.195.132:2181,192.168.195.133:2181,192.168.195.134:2181</value>
   </property>
 <property>
    <name>hbase.coprocessor.abortonerror</name>
    <value>false</value>
    </property>
</configuration>

4.hbase-env.sh

export JAVA_HOME=/usr/local/java/jdk1.8.0_161

export HBASE_CLASSPATH=/usr/local/hadoop/etc/hadoop

export HBASE_MANAGES_ZK=false

export TZ="Asia/Shanghai"

5.配置regionservers

hadoop1
hadoop2
hadoop3

6.拷贝到其他节点上

scp -rp hbase路径  hadoop2:你想安装的路径

截至这里，应该已经安装好了

先启动zookeeper,hdfs

zkServer.sh start
查看zookeeper状态
zkServer.sh status
启动hdfs
start-dfs.sh
查看任务是否正常
jps
正常情况：
[root@bigboss1 ~]# jps
8481 Jps
4898 HMaster
5383 Main
5018 HRegionServer
3867 NameNode
2476 QuorumPeerMain
3964 DataNode
4140 JournalNode
4668 NodeManager
4317 DFSZKFailoverController

启动hbase

[root@bigboss1 targz]# start-hbase.sh

进入hbase,status查看状态正常,create一个表试试！

[root@bigboss1 targz]# hbase shell

ok

但是，可能您会出错，你试试以下操作

1.关闭防火墙

[root@Slave1 ~]# firewall-cmd –state        查看防火墙状态
running
[root@Slave1 ~]# systemctl stop firewalld.service    关闭防火墙
[root@Slave1 ~]# systemctl disable firewalld.service  配置开机不启动防火墙
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
[root@Slave1 ~]# firewall-cmd --state
not running

2. 关闭selinux,修改/etc/selinux/config. 将SELINUX=enforcing改为SELINUX=disabled
