【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

starting master, logging to /opt/programs/hbase-1.2.0/logs/hbase-root-master-bigboss1.out

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
