Standalone hom yog lub neej ntawd hom kev ua haujlwm ntawm Hadoop thiab nws khiav ntawm ib leeg (ib lub node yog koj lub tshuab). HDFS thiab YARN tsis khiav mus standalone hom . Pseudo-Distributed hom sawv nruab nrab ntawm cov standalone hom thiab faib tag nrho hom nyob rau hauv ib pawg ntau lawm.
Yog li ntawd, hom standalone yog dab tsi?
Standalone hom yog qhov yooj yim tshaj plaws hom , qhov twg ib tug txheej txheem yog lub luag hauj lwm rau executing tag nrho cov connectors thiab cov hauj lwm. Txij li nws yog ib txoj kev, nws yuav tsum tau configuration tsawg heev.
Tsis tas li ntawd, hom kev faib tawm tag nrho hauv Hadoop yog dab tsi? • Cov ntaub ntawv siv thiab faib nyob rau hauv ntau lub nodes. Hauv Hadoop kev loj hlob, txhua Hadoop Hom nws muaj nws cov txiaj ntsig thiab qhov tsis zoo. Tseeb tiag hom kev faib tawm tag nrho yog tus uas Hadoop feem ntau paub tab sis dua tsis muaj qhov taw tes rau kev koom nrog cov peev txheej thaum nyob rau hauv kev sim lossis debugging theem.
Ib yam li ntawd, koj tuaj yeem nug, uas yog cov kev tso cai ua haujlwm hauv Hadoop?
Txawv Hadoop Hom
- Hom Hauv zos lossis hom Standalone. Standalone hom yog lub neej ntawd hom uas Hadoop khiav.
- Pseudo-distributed hom. pseudo-distribute hom kuj tseem hu ua ib pawg ntawm ib leeg qhov twg NameNode thiab DataNode yuav nyob ntawm tib lub tshuab.
- Fully-Distributed Mode (Multi-Node Cluster)
Ib leeg yog dab tsi?
Tib Node los yog Psuedo-Distributed Cluster yog ib qho uas tag nrho cov daemons tseem ceeb (xws li NameNode, DataNode, JobTracker thiab TaskTracker) khiav ntawm tib lub tshuab. Lub default replication factor rau ib tug multi node pawg yog 3. Nws yog ib txwm siv rau tag nrho pawg kev loj hlob ntawm hadoop daim ntawv thov thiab tej yaam num.

Cov neeg hais lus sau ntawv yog cov ntawv qhia uas tus neeg nthuav qhia siv thaum nthuav qhia qhov kev nthuav qhia. Lawv pab tus neeg nthuav qhia nco txog cov ntsiab lus tseem ceeb thaum muab kev nthuav qhia. Lawv tshwm sim ntawm tus swb thiab tuaj yeem pom tsuas yog los ntawm tus tshaj tawm thiab tsis yog cov neeg tuaj saib
Tus neeg siv hom thiab kernel hom yog dab tsi hauv OS?
Lub kaw lus yog nyob rau hauv cov neeg siv hom thaum lub operating system khiav ib tug neeg siv daim ntawv thov xws li tuav cov ntawv nyeem. Kev hloov pauv ntawm hom neeg siv mus rau hom ntsiav tshwm sim thaum daim ntawv thov thov kev pab ntawm kev khiav hauj lwm los yog kev cuam tshuam lossis kev hu xov tooj tshwm sim. Lub hom me ntsis yog teem rau 1 hauv hom neeg siv
