hadoop生态系统
HBase简介
–HBase–HadoopDatabase,是一个高可靠性、高性能、面向列、可伸缩、实时读写的分布式数据库
–利用HadoopHDFS作为其文件存储系统,利用HadoopMapReduce来处理HBase中的海量数据,利用Zookeeper作为其分布式协同服务
(1)安装的前提条件
此安装是在阿里云服务器上安装的,且java环境已经配好,hadoop和zookeeper都已经安装好并成功启动
(2)下载hbase-1.1.3-bin.tar.gz,上传并解压
进入conf目录下
1.在hbase-env.sh中配置JAVA_HOME
2.配置hbase-site.xml如下
<property>
<name>hbase.rootdir</name>
<value>file:///opt/hbase</value> //hbase根目录
</property>
<property>
<name>hbase.zookeeper.property.dataDir</name>
<value>/opt/zookeeper</value> //zookeeper根目录,要启动
</property>
(3)启动hbase
进入bin/目录
[[email protected]]# ./start-hbase.sh ./stop-hbase.sh
startingmaster, logging to /home/tong/hbase-1.1.3/bin/../logs/hbase-tong-master-tong.out
[[email protected]]# jps
2442SecondaryNameNode
2148NameNode
2284-- process information unavailable
9112Jps
1074Application
7868QuorumPeerMain
2241DataNode
8848 HMaster
可以看到启动成功了
(4)测试hbase的shell
[[email protected] bin]# ./hbase shell

扩展:让浏览器访问hbase
#vim hbase-site.xml 添加以下内容
<property>
<name>hbase.master.info.port</name>
<value>60010</value> //端口,任选
</property>
<property>
<name>hbase.master.info.bindAddress</name>
<value>ip</value>
</property>
# vim/etc/sysconfig/iptables //让60010通过
# serviceiptables restart //重启网卡
就可以在浏览器中访问了,浏览器访问http://ip:60010/
至此,hbase的单机安装就结束了
