1.启动hbase， 进入hbase文件夹下面的bin文件夹，然后执行命令：
hbase shell [root@hadoop0 bin]# hbase shell
HBase Shell; enter 'help <RETURN >' for list of supported commands.
Type "exit<RETURN>" to leave the HBase Shell
Version 0.98 .12 .1 -hadoop1, rb00ec5da604d64a0bdc7d92452b1e0559f0f5d73, Sun May 17 12 :22 :29 PDT 2015
hbase(main):001 :0 > 2。创建表：
create 'users' ,'user_id' , 'address' , 'info' 表users,三个列簇：user_id, address, info
3.查看所有表：list
hbase (main ):003 :0 > list
TABLE
users
1 row (s ) in 0.0400 seconds 4.查看表结构：describe 'users'
hbase(main):004 :0 > describe 'users'
Table users is ENABLED
users
COLUMN FAMILIES DESCRIPTION
{NAME => 'address' , DATA_BLOCK_ENCODING => 'NONE' , BLOOMFILTER => 'ROW' , REPLICATION_SCOPE => '0' , VERSIONS => '1' , COMPRESSION => 'NONE' , MIN_VERSIONS => '0' , TTL => 'FORE
VER' , KEEP_DELETED_CELLS => 'FALSE' , BLOCKSIZE => '65536' , IN_MEMORY => 'false' , BLOCKCACHE => 'true' }
{NAME => 'info' , DATA_BLOCK_ENCODING => 'NONE' , BLOOMFILTER => 'ROW' , REPLICATION_SCOPE => '0' , VERSIONS => '1' , COMPRESSION => 'NONE' , MIN_VERSIONS => '0' , TTL => 'FOREVER

3 row(s) in 0.1000 seconds5.删除表：
表不能直接删除，需要先进行disable操作：
如果直接删除会报下面的错误：
hbase(main):007 :0 > drop 'user_tmp'
ERROR: Table user_tmp is enabled. Disable it first .
Here is some help for this command :the named table. Table must first be disabled:
hbase> drop 't1'
hbase> drop 'ns1:t1' 应该先disable：
hbase(main):008 :0 > disable 'user_tmp'
0 row(s) in 1.4120 seconds hbase(main):010 :0 > drop 'user_tmp'
0 row(s) in 0.2320 seconds 6.查看表是否存在：
hbase(main):013 :0 > exists 'users'
Table users does exist
0 row(s) in 0.0330 seconds 7.查看是否禁止：
hbase(main):016 :0 > is_enabled 'users'
true
0 row(s) in 0.0410 seconds hbase(main):002 :0 > is_disabled 'users'
false
0 row(s) in 0.0270 seconds 7.插入数据：
hbase(main):001 :0 > put 'users' , 'xiaoming' ,'info:company' ,'baidu' 8.查看表中的数据：
scan 'users' 9.获得小明的信息：
hbase(main):003 :0 > get 'users' ,'xiaoming'
COLUMN CELL
info:age timestamp=1433712506712 , value =22
info:company timestamp=1433712630400 , value =baidu
2 row(s) in 0.0560 seconds 只查看年龄：
hbase(main):004 :0 > get 'users' ,'xiaoming' ,'info:age'
COLUMN CELL
info:age timestamp=1433712506712 , value =22
1 row(s) in 0.0280 seconds 10.更新记录：
hbase(main):007 :0 > put 'users' ,'xiaoming' ,'info:age' ,'24'
0 row(s) in 0.0140 seconds 现在查看年龄就是最新的年龄：
hbase(main):009 :0 > get 'users' ,'xiaoming' ,'info:age'
COLUMN CELL
info:age timestamp=1433713054227 , value =24
1 row(s) in 0.0140 seconds 怎么查看历史记录呢？：
查看上一个数据：
hbase(main):011 :0 > get 'users' ,'xiaoming' ,{COLUMN=>'info:age' ,VERSIONS=>2 }显示时间戳数据：
hbase(main):016 :1 > get 'users' ,'xiaoming' ,{COLUMN=>'info:age' ,TIMESTAMP=>1433713054227 }删除数据：
delete 'users' ,'xiaoming' ,'info:age'
