本篇文章給大家分享的是有關(guān)HBASE中有哪些常用的shell命令,小編覺得挺實(shí)用的,因此分享給大家學(xué)習(xí),希望大家閱讀完這篇文章后可以有所收獲,話不多說,跟著小編一起來看看吧。
創(chuàng)新互聯(lián)服務(wù)項(xiàng)目包括仁布網(wǎng)站建設(shè)、仁布網(wǎng)站制作、仁布網(wǎng)頁制作以及仁布網(wǎng)絡(luò)營銷策劃等。多年來,我們專注于互聯(lián)網(wǎng)行業(yè),利用自身積累的技術(shù)優(yōu)勢、行業(yè)經(jīng)驗(yàn)、深度合作伙伴關(guān)系等,向廣大中小型企業(yè)、政府機(jī)構(gòu)等提供互聯(lián)網(wǎng)行業(yè)的解決方案,仁布網(wǎng)站推廣取得了明顯的社會效益與經(jīng)濟(jì)效益。目前,我們服務(wù)的客戶以成都為中心已經(jīng)輻射到仁布省份的部分城市,未來相信會繼續(xù)擴(kuò)大服務(wù)區(qū)域并繼續(xù)獲得客戶的支持與信任!1、首先給出本次操作的數(shù)據(jù)
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(zhí)行,創(chuàng)建表,增加數(shù)據(jù)操作,執(zhí)行腳本 /bin/hbase shell ./student.txt,然后查看內(nèi)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=zhao 3 row(s) in 0.1940 seconds
3、修改操作 也是用put命令,就是重新添加內(nèi)容把,把以前的內(nèi)容覆蓋。
格式 put 't1', 'r1', 'c1', 'value'
命令 put 'student','1','info:age','18'
結(jié)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=wang 5 row(s) in 0.0110 seconds
4、刪除操作,分為刪除單元格的內(nèi)容,和整行刪除
單元格
hbase(main):012:0> delete 'student','1','info:name' 0 row(s) in 0.0800 seconds hbase(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=1 4 row(s) in 0.0120 seconds
整行
hbase(main):023:0> deleteall 'student','1' 0 row(s) in 0.0260 seconds hbase(main):024:0> get 'student','1' COLUMN CELL 0 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=yang 5 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=yang 3 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=21 1 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=22 2 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=CBD 1 row(s) in 0.0170 seconds
