Hadoop yog qhov qhib-qhov software moj khaum rau khaws cov ntaub ntawv thiab khiav daim ntawv thov ntawm pawg ntawm cov khoom kho vajtse. Nws muab cov ntaub ntawv khaws cia loj heev rau txhua yam ntaub ntawv, kev ua haujlwm loj heev thiab muaj peev xwm los daws cov haujlwm tsis muaj kev txwv tsis sib xws lossis cov haujlwm.
Cov lus nug tseem yog, Hadoop zoo rau dab tsi?
Hadoop yog qhov qhib-qhov, Java-raws li kev siv ntawm cov ntaub ntawv sib koom ua ke hu ua HDFS, uas tso cai rau koj los ua tus nqi tsim nyog, txhim khu kev qha, thiab ua kom muaj peev xwm faib tau. HDFS architecture yog qhov ua txhaum loj heev thiab tsim los siv rau ntawm cov khoom siv qis.
Qhov thib ob, Hadoop thiab Cov Ntaub Ntawv Loj yog dab tsi? Hadoop yog ib qho qhib software moj khaum siv rau khaws cia thiab ua Cov ntaub ntawv loj nyob rau hauv ib qho kev faib rau loj pawg ntawm cov khoom kho vajtse. Hadoop tau tsim, raws li daim ntawv sau los ntawm Google ntawm MapReduce system thiab nws siv cov ntsiab lus ntawm kev ua haujlwm.
Kuj paub, Hadoop yog dab tsi thiab nws ua haujlwm li cas?
Hadoop puas faib ua haujlwm rau cov ntaub ntawv loj loj thoob plaws pawg ntawm cov khoom lag luam thiab ua haujlwm ntawm ntau lub tshuab ib txhij. Txhawm rau ua cov ntaub ntawv, tus neeg siv yuav xa cov ntaub ntawv thiab cov kev pab cuam rau Hadoop . HDFS khaws cov ntaub ntawv thaum MapReduce txheej txheem cov ntaub ntawv thiab xov paj faib cov dej num.
Dab tsi yog cov ntawv thov ntawm Hadoop?
Apache Hadoop yog qhov chaw qhib software lub moj khaum siv los tsim cov ntaub ntawv ua cov ntawv thov uas raug tua nyob rau hauv ib puag ncig kev faib xam. Cov ntawv thov tsim siv HADOOP tau khiav ntawm cov ntaub ntawv loj uas tau muab faib thoob plaws pawg ntawm cov khoom siv hauv computer. Cov khoom siv computer yog pheej yig thiab dav muaj.

Dab tsi ntawm cov hauv qab no yog qhov zoo ntawm kev siv cov khoom siv pom kev hauv kev hais lus?
Qhov txiaj ntsig tseem ceeb ntawm kev siv cov khoom siv pom hauv koj cov lus hais yog tias lawv ua kom cov neeg tuaj saib muaj kev txaus siab, hloov kev mloog ntawm tus neeg hais lus, thiab ua rau tus neeg hais lus muaj kev ntseeg siab ntau dua hauv kev nthuav qhia tag nrho
Dab tsi yog qhov sib txawv loj ntawm kev txheeb xyuas qhov yuam kev thiab kev kho cov lej yuam kev?
Ob qhov kev tshawb nrhiav qhov yuam kev thiab kev kho qhov yuam kev yuav tsum muaj qee qhov ntawm cov ntaub ntawv rov qab xa mus nrog cov ntaub ntawv tiag tiag; kev kho yuav tsum muaj ntau tshaj li kev tshawb nrhiav. Parity bits yog ib txoj hauv kev yooj yim rau kev tshawb nrhiav qhov yuam kev. Ib qho parity me ntsis yog ib qho ntxiv me ntsis xa nrog cov ntaub ntawv uas tsuas yog 1-ntsis suav ntawm cov ntaub ntawv
Dab tsi yog qhov txawv ntawm cov neeg siv kev paub thiab kev paub ntawm cov neeg siv khoom?
User Experience (UX) cuam tshuam nrog tib neeg cuam tshuam nrog koj cov khoom thiab cov kev paub uas lawv tau txais los ntawm kev sib cuam tshuam. Customer Experience (CX), incontrast, encompasses tag nrho cov kev sib cuam tshuam ib tug neeg muaj nrog koj hom
Dab tsi yog qhov kev txwv kev ncaj ncees piav qhia txog kev ncaj ncees lossis kev txwv txawv teb chaws?
Kev lees paub ncaj ncees xav kom tus yuam sij txawv teb chaws yuav tsum muaj tus yuam sij tseem ceeb sib xws lossis nws yuav tsum yog null. Qhov kev txwv no tau teev tseg ntawm ob lub rooj (niam txiv thiab menyuam); nws tuav cov ntawv xov xwm ntawm kab hauv cov rooj no. Nws txhais tau hais tias kev siv los ntawm kab hauv ib lub rooj mus rau lwm lub rooj yuav tsum siv tau
Dab tsi yog qhov tseem ceeb ntawm kev siv kev coj ncaj ncees rau cov ntaub ntawv kev ruaj ntseg?
Rau cov kws tshaj lij kev ruaj ntseg cov ntaub ntawv, muaj ob lub hom phiaj tseem ceeb thaum nws los txog rau cov ntaub ntawv tseem ceeb: tiv thaiv nws thiab paub txog nws qhov chaw. Cov koom haum tsis tuaj yeem xav tias cov ntaub ntawv raug cai lossis tau txais los ntawm kev coj ncaj ncees
