1、  启动hbase shell

(1)   确保hadoop 、zookeeper启动

(2)   确保hbase启动

(3)   执行hbase shell命令(在已经配置环境变量的情况下)

2、  查看表

(1)list

hbase(main):001:0> list 'test'
TABLE                                                                                                                                                                                          
test                                                                                                                                                                                           
1 row(s) in 0.3460 seconds

=> ["test"]

(2)exists

hbase(main):002:0> exists 'test'
Table test does exist                                                                                                                                                                          
0 row(s) in 0.1110 seconds

3、  新建表

create 'test',{NAME => 'f1',VERSIONS => 4}

4、  修改表(alter)

alter 'test',NAME => 'f1',VERSIONS =>3

5、删除表(删除之前要先disable)

disable 'test'

drop 'test'

6、描述表

describe 'test'(desc 'test')

7、插入数据

put 'test','row1','f1:name','zhangsan'

8、表数据获取(scan/get)

scan 'test'

get 'test',{COLUMN=>'f1:name',VERSIONS => 3}

9、表数据删除(deleteall删除整行)

deleteall't1','row1'
