安装配置

Hbase需要zookeeper的支持，本博客有专门写zookeeper安装教程的可参看。
单机安装的话可以用Hbase自带的，伪分布安装的话自己安装一个Zookeeper即可。

下面HBASE_MANAGES_ZK=false: false使用自带的zookeeper,否则需要配置独立的zookeeper。

mkdir -p /opt/hbase
cd /opt/hbase
sudo wget http://mirrors.cnnic.cn/apache/hbase/stable/hbase-1.1.5-bin.tar.gz


#编辑{HBASE_HOME}/conf/hbase-env.sh，设置JAVA_HOME和HBASE_CLASSPATH
export JAVA_HOME=/opt/java/jdk1.7.0_79 
export HBASE_CLASSPATH=/opt/hadoop/hbase/hbase-1.1.5/conf 
export HBASE_MANAGES_ZK=false

修改hbase-site.xml

<property>
        <name>hbase.rootdir</name>
        <value>hdfs://172.16.22.251:9005/hbase</value>
    </property>
    <property>
        <name>hbase.cluster.distributed</name>
        <value>true</value>
    </property>
    <property>
        <name>hbase.master</name>
        <value>localhost:60000</value>
    </property>
    <property>
        <name>hbase.zookeeper.quorum</name>
        <value>localhost</value>
    </property>
    <property>
    <name>hbase.zookeeper.property.dataDir</name>
    <value>/home/hadoop/hadoop_tmp/zookeeper</value>
  </property>

hbase.rootdir:需要和hadoop中core-site.xml中fs.default.name中的路径相同,这里配置到hdfs上，不配置到本地。
hbase.cluster.distributed:hbase.cluster.distributed指定了Hbase的运行模式。false是单机模式，true是分布式模式。
hbase.zookeeper.quorum是Zookeeper集群的地址列表，用逗号分割。
hbase.zookeeper.property.clientPort：zookeeper客户端端口。

启动Hbase Master

[hadoop@localhost bin]$ ./start-hbase.sh
starting master, logging to /opt/hadoop/hbase/hbase-1.1.5/logs/hbase-hadoop-master-localhost.localdomain.out
starting regionserver, logging to /opt/hadoop/hbase/hbase-1.1.5/logs/hbase-hadoop-1-regionserver-localhost.localdomain.out

验证Hbase Master是否启动成功

http://172.16.22.251:16010(各版本可能默认端口不一样)

Hbase Shell

启动Hbase Shell后查看

[hadoop@localhost bin]$ hbase shell
HBase Shell; enter 'help<RETURN>' for list of supported commands.
Type "exit<RETURN>" to leave the HBase Shell
Version 1.1.5, r239b80456118175b340b2e562a5568b5c744252e, Sun May  8 20:29:26 PDT 2016

hbase(main):001:0> status
1 servers, 0 dead, 2.0000 average load

创建一个数据库

hbase(main):002:0> create 'test', 'id', 'name', 'address', 'info'
0 row(s) in 1.4900 seconds

=> Hbase::Table - test
hbase(main):003:0> list
TABLE
test
1 row(s) in 0.0250 seconds

hbase(main):005:0> describe 'test'
Table test is ENABLED
test

查看Hdfs上的hbase数据

[hadoop@localhost bin]$ hdfs dfs -ls /hbase
