| 创建表 | create '表名称', '列族名称1','列族名称2','列族名称N' |
| 添加记录 | put '表名称', '行名称', '列名称:', '值' |
| 查看记录 | get '表名称', '行名称' |
| 查看表中的记录总数 | count '表名称' |
| 删除记录 | delete '表名' ,'行名称' , '列名称' |
| 删除一张表 | 先要屏蔽该表，才能对该表进行删除，第一步 disable '表名称' 第二步 drop '表名称' |
| 查看所有记录 | scan "表名称" |
| 查看某个表某个列中所有数据 | scan "表名称" , {COLUMNS=>'列族名称:列名称'} |
| 更新记录 | 就是重写一遍进行覆盖 |
