【hadoop】【demo】HBase shell

t_student		cf1			cf2
	rowkey	id	name	...	age	address	...
	r1	1001	Kitty		20	/
	r2	1002	Jack		/	NanJing

1.创建用户test_super(有supergroup权限)，test_guest(无supergroup权限)

2.连接用户 test_super 并创建表 't_student'

kinit test_super

hbase shell

whoami #查看用户权限

list #查看用户下表

create 't_student','cf1'

describe 't_student'

user_permission 't_student' #权限：action=ADMIN

grant 'user_guest','CRW', 't_student' #授权用户 user_guest 对 't_student' 有CRW 权限

quit

3.连接用户 test_guest 并修改表 't_student'

kinit test_guest

hbase shell

whoami #查看用户权限

list #查看用户下表

describe 't_student'

disable 't_student'

alter 't_student',{NAME=>'cf1',NAME=>'cf2'} #修改表结构

enable 't_student'

#新增表数据：此段语句可以写入 test.sh

vi test.sh

输入以下内容：

hbase shell <<EOF

put 't_student','r1','cf1:id','1001'

put 't_student','r1','cf1:name','Kitty'

put 't_student','r1','cf2:age','20'

put 't_student','r2','cf1:id','1002'

put 't_student','r2','cf1:name','Jack'

put 't_student','r2','cf2:age','22'

put 't_student','r2','cf2:address','NanJing'

EOF

执行test.sh

sh test.sh

#修改/删除表数据

put 't_student','r1','cf1:name','Kitty'

put 't_student','r1','cf1:name','Amy'

#查询表数据

scan 't_student' #查全表

scan 't_student',{LIMIT=>1} #查1行

get 't_student','r1'

get 't_student','r2'

get 't_student','r1',{COLUMN=> ['cf1','cf2']}

get 't_student','r2',{COLUMN=> ['cf1','cf2']}

get 't_student','r1',{COLUMN=> ['cf1:id','cf1:name','cf2:age']}

get 't_student','r2',{COLUMN=> ['cf1:id','cf1:name','cf2:address']}

get 't_student','r1',{COLUMN=> ['cf1:id','cf1:name']}

get 't_student','r1',{COLUMN=> 'cf1:name'}

get 't_student','r1','cf1:id','cf1:name'

get 't_student','r1','cf1:name'

get 't_student','r1','cf1:id','cf1:name','cf2:age'

get 't_student','r2','cf1:id','cf1:name','cf2:address'

disable 't_student'

drop 't_student'
