hbase表结构及安装部署

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

export JAVA_HOME=/usr/lib/java/java-7-sun
export HBASE_MANAGES_ZK=false指定外部的zk

</property>
<!--指定hbase是分布式的-->

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
