HBASE 常用shell命令，增刪改查

首先給出本次操作的資料

create 'student','info','address'put 'student','1','info:age','20'put 'student','1','info:name','wang'put 'student','1','info:class','1'put 'student','1','address:city','zhengzhou'put 'student','1','address:area','High-tech zone'put 'student','2','info:age','21'put 'student','2','info:name','yang'put 'student','2','info:class','1'put 'student','2','address:city','beijing'put 'student','2','address:area','CBD'put 'student','3','info:age','22'put 'student','3','info:name','zhao'put 'student','3','info:class','2'put 'student','3','address:city','shanghai'put 'student','3','address:area','pudong'scan 'student'

2.首先執行，建立表，增加資料操作，執行指令碼 /bin/hbase shell ./student.txt,然後查看內容 scan ‘student’

hbase(main):001:0> scan 'student'ROW                        COLUMN+CELL 1                         column=address:area, timestamp=1491533426260, value=High-tech zone 1                         column=address:city, timestamp=1491533426239, value=zhengzhou 1                         column=info:age, timestamp=1491533426179, value=20 1                         column=info:class, timestamp=1491533426218, value=1 1                         column=info:name, timestamp=1491533426211, value=wang 2                         column=address:area, timestamp=1491533426297, value=CBD 2                         column=address:city, timestamp=1491533426292, value=beijing 2                         column=info:age, timestamp=1491533426269, value=21 2                         column=info:class, timestamp=1491533426287, value=1 2                         column=info:name, timestamp=1491533426277, value=yang 3                         column=address:area, timestamp=1491533426329, value=pudong 3                         column=address:city, timestamp=1491533426323, value=shanghai 3                         column=info:age, timestamp=1491533426305, value=22 3                         column=info:class, timestamp=1491533426317, value=2 3                         column=info:name, timestamp=1491533426311, value=zhao3 row(s) in 0.1940 seconds

3.修改操作 也是用put命令，就是重新新增內容把，把以前的內容覆蓋。

格式 put 't1', 'r1', 'c1', 'value'

 命令 put 'student','1','info:age','18'

 結果hbase(main):010:0> get 'student','1'COLUMN                     CELL address:area              timestamp=1491533426260, value=High-tech zone address:city              timestamp=1491533426239, value=zhengzhou info:age                  timestamp=1491533823331, value=18 info:class                timestamp=1491533426218, value=1 info:name                 timestamp=1491533426211, value=wang5 row(s) in 0.0110 seconds

4.刪除操作，分為刪除儲存格的內容，和整行刪除
儲存格

hbase(main):012:0> delete 'student','1','info:name'0 row(s) in 0.0800 secondshbase(main):014:0> get 'student','1'COLUMN                     CELL address:area              timestamp=1491533426260, value=High-tech zone address:city              timestamp=1491533426239, value=zhengzhou info:age                  timestamp=1491533823331, value=18 info:class                timestamp=1491533426218, value=14 row(s) in 0.0120 seconds

整行

hbase(main):023:0> deleteall 'student','1'0 row(s) in 0.0260 secondshbase(main):024:0> get 'student','1'COLUMN                     CELL0 row(s) in 0.0070 seconds

5.查詢

單行查詢

hbase(main):026:0> get 'student','2'COLUMN                     CELL address:area              timestamp=1491533426297, value=CBD address:city              timestamp=1491533426292, value=beijing info:age                  timestamp=1491533426269, value=21 info:class                timestamp=1491533426287, value=1 info:name                 timestamp=1491533426277, value=yang5 row(s) in 0.0190 seconds

指定列族

hbase(main):028:0> get 'student', '2', {COLUMN => 'info'}COLUMN                     CELL info:age                  timestamp=1491533426269, value=21 info:class                timestamp=1491533426287, value=1 info:name                 timestamp=1491533426277, value=yang3 row(s) in 0.0150 seconds

指定列名

hbase(main):029:0> get 'student', '2', {COLUMN => 'info:age'}COLUMN                     CELL info:age                  timestamp=1491533426269, value=211 row(s) in 0.0080 seconds

使用scan，指定startrow

hbase(main):031:0>  scan 'student', {COLUMNS => ['info:age', 'address'], LIMIT => 10, STARTROW => '2'}ROW                        COLUMN+CELL 2                         column=address:area, timestamp=1491533426297, value=CBD 2                         column=address:city, timestamp=1491533426292, value=beijing 2                         column=info:age, timestamp=1491533426269, value=21 3                         column=address:area, timestamp=1491533426329, value=pudong 3                         column=address:city, timestamp=1491533426323, value=shanghai 3                         column=info:age, timestamp=1491533426305, value=222 row(s) in 0.0190 seconds

scan指定過濾

hbase(main):005:0> scan 'student',{FILTER=>"(TimestampsFilter (1491533426297))"}ROW                        COLUMN+CELL 2                         column=address:area, timestamp=1491533426297, value=CBD1 row(s) in 0.0170 seconds
