HBase(04)——HBase基本shell命令
進入hbase命令列 ./hbase shell
顯示hbase中的表 list
建立user表,包含info、data兩個列族 create ‘user’, ‘info’, ‘data’ 或者 create ‘user’, {NAME => ‘info’, VERSIONS => ‘3’},{NAME => ‘data’}
向user表中插入資訊,row key為rk0001,列族info中新增name列標示符,值為zhangsan put ‘user’, ‘rk0001’, ‘info:name’, ‘zhangsan’
向user表中插入資訊,row key為rk0001,列族info中新增gender列標示符,值為female put ‘user’, ‘rk0001’, ‘info:gender’, ‘female’
向user表中插入資訊,row key為rk0001,列族info中新增age列標示符,值為20 put ‘user’, ‘rk0001’, ‘info:age’, 20
向user表中插入資訊,row key為rk0001,列族data中新增pic列標示符,值為picture put ‘user’, ‘rk0001’, ‘data:pic’, ‘picture’
獲取user表中row key為rk0001的所有資訊 get ‘user’, ‘rk0001’
獲取user表中row key為rk0001,info列族的所有資訊 get ‘user’, ‘rk0001’, ‘info’
獲取user表中row key為rk0001,info列族的name、age列標示符的資訊 get ‘user’, ‘rk0001’, ‘info:name’, ‘info:age’
獲取user表中row key為rk0001,info、data列族的資訊 get ‘user’, ‘rk0001’, ‘info’, ‘data’ get ‘user’, ‘rk0001’, {COLUMN => [‘info’, ‘data’]}
get ‘user’, ‘rk0001’, {COLUMN => [‘info:name’, ‘data:pic’]}
獲取user表中row key為rk0001,列族為info,版本號最新5個的資訊 get ‘user’, ‘rk0001’, {COLUMN => ‘info’, VERSIONS => 2} get ‘user’, ‘rk0001’, {COLUMN => ‘info:name’, VERSIONS => 5} get ‘user’, ‘rk0001’, {COLUMN => ‘info:name’, VERSIONS => 5, TIMERANGE => [1392368783980, 1392380169184]}
獲取user表中row key為rk0001,cell的值為zhangsan的資訊 get ‘people’, ‘rk0001’, {FILTER => “ValueFilter(=, ‘binary:zhangsan’)”}
獲取user表中row key為rk0001,列標示符中含有a的資訊 get ‘people’, ‘rk0001’, {FILTER => “(QualifierFilter(=,‘substring:a’))”}
put ‘user’, ‘rk0002’, ‘info:name’, ‘fanbingbing’ put ‘user’, ‘rk0002’, ‘info:gender’, ‘female’ put ‘user’, ‘rk0002’, ‘info:nationality’, ‘中國’ get ‘user’, ‘rk0002’, {FILTER => “ValueFilter(=, ‘binary:中國’)”}
查詢user表中的所有資訊 scan ‘user’
查詢user表中列族為info的資訊 scan ‘user’, {COLUMNS => ‘info’} scan ‘user’, {COLUMNS => ‘info’, RAW => true, VERSIONS => 5} scan ‘person’, {COLUMNS => ‘info’, RAW => true, VERSIONS => 3}
查詢user表中列族為info和data的資訊 scan ‘user’, {COLUMNS => [‘info’, ‘data’]} scan ‘user’, {COLUMNS => [‘info:name’, ‘data:pic’]}
查詢user表中列族為info、列標示符為name的資訊 scan ‘user’, {COLUMNS => ‘info:name’}
查詢user表中列族為info、列標示符為name的資訊,並且版本最新的5個 scan ‘user’, {COLUMNS => ‘info:name’, VERSIONS => 5}
查詢user表中列族為info和data且列標示符中含有a字元的資訊 scan ‘user’, {COLUMNS => [‘info’, ‘data’], FILTER => “(QualifierFilter(=,‘substring:a’))”}
查詢user表中列族為info,rk範圍是[rk0001, rk0003)的資料 scan ‘people’, {COLUMNS => ‘info’, STARTROW => ‘rk0001’, ENDROW => ‘rk0003’}
查詢user表中row key以rk字元開頭的 scan ‘user’,{FILTER=>“PrefixFilter(‘rk’)”}
查詢user表中指定範圍的資料 scan ‘user’, {TIMERANGE => [1392368783980, 1392380169184]}
刪除資料 刪除user表row key為rk0001,列標示符為info:name的資料 delete ‘people’, ‘rk0001’, ‘info:name’ 刪除user表row key為rk0001,列標示符為info:name,timestamp為1392383705316的資料 delete ‘user’, ‘rk0001’, ‘info:name’, 1392383705316
清空user表中的資料 truncate ‘people’
修改表結構 首先停用user表 disable ‘user’
新增兩個列族f1和f2 alter ‘people’, NAME => ‘f1’ alter ‘user’, NAME => ‘f2’
啟用表 enable ‘user’
刪除一個列族: alter ‘user’, NAME => ‘f1’, METHOD => ‘delete’ 或 alter ‘user’, ‘delete’ => ‘f1’
新增列族f1同時刪除列族f2 alter ‘user’, {NAME => ‘f1’}, {NAME => ‘f2’, METHOD => ‘delete’}
將user表的f1列族版本號改為5 alter ‘people’, NAME => ‘info’, VERSIONS => 5 啟用表 enable ‘user’
刪除表 disable ‘user’ drop ‘user’
查詢資料 get ‘person’, ‘rk0001’, {FILTER => “ValueFilter(=, ‘binary:中國’)”} get ‘person’, ‘rk0001’, {FILTER => “(QualifierFilter(=,‘substring:a’))”} scan ‘person’, {COLUMNS => ‘info:name’} scan ‘person’, {COLUMNS => [‘info’, ‘data’], FILTER => “(QualifierFilter(=,‘substring:a’))”} scan ‘person’, {COLUMNS => ‘info’, STARTROW => ‘rk0001’, ENDROW => ‘rk0003’}
scan ‘person’, {COLUMNS => ‘info’, STARTROW => ‘20140201’, ENDROW => ‘20140301’} scan ‘person’, {COLUMNS => ‘info:name’, TIMERANGE => [1395978233636, 1395987769587]} delete ‘person’, ‘rk0001’, ‘info:name’
alter ‘person’, NAME => ‘ffff’ alter ‘person’, NAME => ‘info’, VERSIONS => 10
get ‘user’, ‘rk0002’, {COLUMN => [‘info:name’, ‘data:pic’]}
