Muaj peb hom kev teem sijhawm muaj nyob hauv YARN: FIFO, Peev Xwm thiab Ncaj Ncees. FIFO (ua ntej hauv, ua ntej tawm) yog qhov yooj yim kom nkag siab thiab tsis xav tau kev teeb tsa.

YARN puas yog tus teem sijhawm?

YARN muaj pluggable teem sijhawm tivthaiv Tus ResourceManager ua raws li lub sijhawm teem sijhawm thoob ntiaj teb uas tswj thiab tswj tag nrho cov ntim khoom (peev txheej). Kev teem sijhawm feem ntau yog ib qho teeb meem nyuaj thiab tsis muaj ib txoj cai "zoo tshaj", uas yog vim li cas YARN muab kev xaiv ntawm cov sijhawm teem sijhawm thiab cov cai tswjfwm.

Nws yog lub sijhawm teem sijhawm hauv YARN?

Lub Peev Xwm Scheduler yog siv los ntawm lub neej ntawd (txawm tias Lub Sijhawm Ncaj Ncees yog lub neej ntawd hauv qee qhov kev faib tawm Hadoop, xws li CDH), tab sis qhov no tuaj yeem hloov pauv los ntawm kev teeb tsa xov paj. Resourcemanager.

Lub sijhawm teem sijhawm hauv YARN yog dab tsi?

Lub peev xwm teem sijhawm hauv YARN tso cai rau ntau qhov chaw nyob ntawm Hadoop pawg uas ntau tus neeg siv tuaj yeem faib cov pawg loj… tab sis qhov kev thov siab kawg no yuav tsis tshwm sim ntau zaus, ua rau kev siv cov peev txheej tsis zoo nyob rau lub sijhawm so.

FIFO teem sijhawm hauv YARN yog dab tsi?

FIFO txhais tau tias Thawj Hauv Thawj Tawm. Raws li lub npe qhia, txoj haujlwm xa ua ntej yuav tau txais qhov tseem ceeb los ua. FIFO yog tus queue-based teem sijhawm Yog tias peb teeb tsa Pawg siv Plain Vanilla Hadoop, Thawj Hauv Thawj Tawm (FIFO) yog lub sijhawm teem sijhawm. Muab cov peev txheej raws li lub sijhawm tuaj txog.
