本节内容我们主要讲解下HBase的常用shell操作。首先我我们要启动hbase：

 start-hbase.sh

然后连接到hbase服务器：

 hbase shell

接下来，我们执行一些常用的shell操作：
1）创建表

 #语法格式 create '表名称','列族名称1',''列族名称2',''列族名称N' #比如 create 'table1','cf1','cf2'

执行效果如下：

 hbase:002:0> create 'table1','cf1','cf2' Created table table1 Took 6.3768 seconds => Hbase::Table - table1

2）显示所有表

 list

执行效果如下：

 hbase:003:0> list TABLE table1 1 row(s) Took 0.6862 seconds => ["table1"]

3）增加数据

 #语法格式 put '表名称','ROW值','列族名称:列名','列值' #比如 put 'table1','123','cf1:name','panziye' put 'table1','123','cf2:age','18'

4）查询数据数据

 #语法格式1 scan '表名称' #比如 scan 'table1' #语法格式2 get '表名称','ROW值' #比如 get 'table1','123' #语法格式3 get '表名称','ROW值','列族名称:列名' #比如 get 'table1','123','cf1:name'

执行效果如下：

 hbase:009:0> scan 'table1' ROW COLUMN+CELL 123 column=cf1:name, timestamp=2021-04-26T22:00:36.794, value=panziye 123 column=cf2:age, timestamp=2021-04-26T22:02:33.107, value=18 1 row(s) Took 0.4237 seconds hbase:010:0> get 'table1','123' COLUMN CELL cf1:name timestamp=2021-04-26T22:00:36.794, value=panziye cf2:age timestamp=2021-04-26T22:02:33.107, value=18 1 row(s) Took 0.3048 seconds hbase:011:0> get 'table1','123','cf1:name' COLUMN CELL cf1:name timestamp=2021-04-26T22:00:36.794, value=panziye 1 row(s) Took 0.1682 seconds

5）修改数据

 #语法格式 put '表名称','ROW值','列族名称:列名','新列值' #比如 put 'table1','123','cf2:age','28'

执行效果如下：

 hbase:023:0> put 'table1','123','cf2:age','28' Took 0.0440 seconds hbase:024:0> get 'table1','123' COLUMN CELL cf1:name timestamp=2021-04-26T22:00:36.794, value=panziye cf2:age timestamp=2021-04-26T22:16:04.812, value=28 1 row(s) Took 0.0533 seconds

6）删除数据

 #语法格式 delete '表名称','ROW值','列族名称:列名' #比如 delete 'table1','123','cf2:age'

执行效果如下：

 hbase:031:0> delete 'table1','123','cf2:age' Took 0.0169 seconds hbase:032:0> get 'table1','123' COLUMN CELL cf1:name timestamp=2021-04-26T22:00:36.794, value=panziye cf2:age timestamp=2021-04-26T22:02:33.107, value=18 1 row(s) Took 0.0237 seconds

7）删除表
删除后表之前需要对表进行disable操作，然后再进行drop操作

 #语法格式 disable '表名称' drop '表名称' #比如 disable 'table1' drop 'table1'

执行效果如下：

 hbase:033:0> disable 'table1' Took 3.0554 seconds hbase:034:0> drop 'table1' Took 4.6391 seconds hbase:035:0> list TABLE 0 row(s) Took 0.3247 seconds => []
