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
bin conf hbase-webapps LICENSE.txt README.txt
CHANGES.txt docs lib NOTICE.txt
[root@hadoop04 hbase-0.96.2-hadoop2]# cd conf
[root@hadoop04 conf]# ls
hadoop-metrics2-hbase.properties hbase-policy.xml regionservers
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




hbase.rootdir
hdfs://ns1/hbase



hbase.cluster.distributed
true




hbase.zookeeper.quorum
hadoop01:2181,hadoop02:2181,hadoop03:2181





[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

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
