Hadoop tsis yog a programming lus . Hadoop [uas suav nrog Distributed File system[HDFS] thiab aprocessing engine [Daim ntawv qhia txo/YARN] thiab nws cov ecosystem tau teeb tsa cov cuab yeej uas pab nws ua cov ntaub ntawv loj. Ua haujlwm rau Hadoop , koj xav tau Java yooj yim thiab qee qhov kev nkag siab hauv Computerscience.
Yog li ntawd, yog Hadoop coding?
Apache Hadoop yog ib qho qhib lub moj khaum, uas yog, nws code tuaj yeem hloov kho los ntawm ib qho dawb raws li kev xav tau ntawm kev lag luam. Cov ntaub ntawv loj yog khaws cia hauv HDFS - Hadoop Distributed File System nyob rau hauv ib qho kev faib tawm thoob plaws pawg. Hadoop yog scalable heev li nodes tuaj yeem txuas ntxiv rau txhua tus lej.
Ib yam li ntawd, puas yog Hadoop database? Hadoop tsis yog hom database , tab sis theej ib qho software ecosystem uas tso cai rau kev sib txuas lus sib luag. Nws yog ib tug enabler ntawm tej yam NoSQL faib databases (xws li HBase), uas tuaj yeem tso cai rau cov ntaub ntawv nthuav tawm thoob plaws ntau txhiab tus servers nrog kev txo qis hauv kev ua haujlwm.
Yog li ntawd, cov ntaub ntawv loj yog cov lus programming?
Tsis yog, Cov ntaub ntawv loj tsis yog a programming lus . Txawm li cas los xij, txhawm rau khaws cov kev xav tawm ntawm cov ntaub ntawv loj Tej zaum koj yuav xav kom muaj qee qhov kev paub coding yooj yim. Nyob rau hauv ib tug lay man lus Big Data yog ib lo lus siv rau ntau yam ntawm cov qauv, unstructured cov ntaub ntawv uas yog tsim los ntawm theelectronics li peb siv hnub nyob rau hauv hnub tawm.
Yam lus twg yuav tsum muaj rau cov ntaub ntawv loj?
Cov thawj tswj hwm hnub no yog R, Python, Scala, SAS, Hadoop yam lus (Npua, Hive, thiab lwm yam), thiab tau kawg, Java. Thaum kawg suav, ib qho tsis txaus 12 feem pua ntawm cov neeg tsim khoom ua haujlwm nrog cov ntaub ntawv loj tej yaam num xaiv siv Java. Yog li, koj muaj loj npaj rau cov ntaub ntawv loj.

Lub hom phiaj ntawm hom lus hom lus yog dab tsi?
Hom Lus Specification. Ib Hom Lus Qhia Tshwj Xeeb (CLS) yog ib daim ntawv uas hais tias yuav ua li cas cov khoos phis tawj tuaj yeem hloov mus rau hauv Cov Lus Qhia Nruab Nrab (CIL) code. Thaum ntau hom lus siv tib bytecode, qhov sib txawv ntawm qhov kev pab cuam tuaj yeem sau ua hom lus sib txawv
Hom programming hom lus twg mus?
Mus (tsis raug hu ua Golang,) yog ib hom lus sau tseg, sau ua lus programming tsim los ntawm Google los ntawm Robert Griesemer, Rob Pike, thiab Ken Thompson. Mus yog syntactically zoo ib yam li C, tab sis nrog lub cim xeeb kev nyab xeeb, khaws khib nyiab, kev ntaus ntawv, thiab CSP-style concurrency
Modular programming pab tau li cas hauv cov lus programming?
Cov txiaj ntsig ntawm kev siv modular programming suav nrog: Tsawg code yuav tsum tau sau. Ib txoj kev tuaj yeem tsim kho rau rov siv dua, tshem tawm qhov yuav tsum tau rov ntaus tus lej ntau zaus. Cov kev pab cuam tuaj yeem tsim tau yooj yim dua vim tias ib pab pawg me cuam tshuam nrog tsuas yog ib feem me me ntawm tag nrho cov cai
Puas yog sau ib hom lus ntawm kev sib txuas lus?
Peb cia siab rau kev sib txuas lus los ntawm kev sib txuas lus nrog ib leeg thiab txhim kho raws li tus neeg. Lo lus hais lus sib txuas lus feem ntau evokes lub tswv yim ntawm kev sib txuas lus, tab sis kev sib txuas lus sau ntawv kuj yog ib feem ntawm kev sib txuas lus. Kev sib txuas lus hais lus thiab tsis hais lus tuaj yeem hais thiab sau
