hbase表结构及安装部署
建表时只需要指定表名和列族
每一行是一条记录， 每一行的字段数是任意的，每一个字段都要指定存储
字段名和字段值，查询某一个字段时，需要指定的坐标：表名--行健--列族
字段名clolumn family 字段
[root@hadoop04 Desktop]# tar -zxvf hbase-0.96.2-hadoop2-bin.tar.gz -C ../app
[root@hadoop04 Desktop]# cd ../app
[root@hadoop04 app]# cd hbase-0.96.2-hadoop2
[root@hadoop04 hbase-0.96.2-hadoop2]# ls

[root@hadoop04 hbase-0.96.2-hadoop2]# cd conf
[root@hadoop04 conf]# ls

hbase-env.cmd                     hbase-site.xml
hbase-env.sh                      log4j.properties
[root@hadoop04 conf]# echo $JAVA_HOME
/usr/lib/java/java-7-sun
[root@hadoop04 conf]# vi hbase-env.sh
export JAVA_HOME=/usr/lib/java/java-7-sun
export HBASE_MANAGES_ZK=false指定外部的zk

[root@hadoop04 conf]# vi hbase-site.xml

<configuration>
<!--指定hbase在hdfs上的存储路径-->
<property>
<name>hbase.rootdir</name>
<value>hdfs://ns1/hbase</value>
</property>
<!--指定hbase是分布式的-->
<property>
<name>hbase.cluster.distributed</name>
<value>true</value>
</property>

<!--指定zk的地址，多个用“，”分割-->
<property>
<name>hbase.zookeeper.quorum</name>
<value>hadoop01:2181,hadoop02:2181,hadoop03:2181</value>
</property>


</configuration>

[root@hadoop04 conf]# vi regionservers
hadoop01
hadoop02
hadoop03
注意要把hadoop 的hdfs-site.xml,core-site.xml放到hbase/conf下
[root@hadoop04 conf]#  cp /home/hadoop/hadoop-2.6.0/etc/hadoop/{core-site.xml,hdfs-site.xml} ./
[root@hadoop05 ~]# mkdir /root/app

[root@hadoop04 app]# scp -r hbase-0.96.2-hadoop2/ hadoop01:/root/app
[root@hadoop04 app]# scp -r hbase-0.96.2-hadoop2/ hadoop02:/root/app
[root@hadoop04 app]# scp -r hbase-0.96.2-hadoop2/ hadoop03:/root/app
[root@hadoop04 app]# hdfs dfsadmin report

启动所有的hbase
分别启动zk
./zkServer.sh start
启动hbase集群
start-dfs.sh
启动hbase，在主节点上运行
start-hbase.sh
通过浏览器访问hbase管理页面
hadoop04:60010
为保证集群的可靠性，要启动多个hmaster
hbase-daemon.sh start master
