Video: Cov phiaj xwm twg yog npua tsim tom qab ua qhov yooj yim parsing thiab tshawb xyuas semantic?

Npua undergo qee cov kauj ruam thaum a Npua Cov ntawv Latin tau hloov mus rau hauv MapReduce cov haujlwm. Tom qab ua qhov yooj yim parsing thiab semantic checking , nws tsim tawm ib qho laj thawj npaj . Qhov laj thawj npaj piav qhia txog cov neeg ua haujlwm logical uas yuav tsum tau ua los ntawm Npua thaum ua tiav.
Ib yam li ntawd, puas yog lub hauv paus rau kev sau thiab khaws cov ntawv qib kev txheeb cais rau npua Latin?
Pig Statistics yog lub hauv paus rau kev sau thiab khaws cov ntawv - qib kev txheeb cais rau npua Latin . Yam ntxwv ntawm Pig Latin scripts thiab qhov tshwm sim MapReduce cov hauj lwm raug sau thaum lub tsab ntawv raug tua.
Ib yam li ntawd, lub neej ntawd hom npua yog dab tsi? Txoj kev ua hom hauv Apache Npua yog: MapReduce Hom : Qhov no yog default hom , uas yuav tsum tau nkag mus rau Hadoop pawg thiab HDFS installation. Txij li thaum, qhov no yog a default hom , nws tsis tas yuav qhia meej -x chij (koj tuaj yeem ua tiav npua LOSSIS npua -x mapreduce). Input thiab output nyob rau hauv no hom muaj nyob rau hauv HDFS.
Tsis tas li ntawd, tus neeg teb xov tooj twg yog siv los tshuaj xyuas qhov schema ntawm kev sib raug zoo?
Tus piav tus neeg teb xov tooj siv saib cov schema ntawm kev sib raug zoo.
Dab tsi yog cov khoom ntawm npua tua ib puag ncig?
Cia peb saib cov khoom tseem ceeb
- Parser. Thaum xub thawj cov Pig Scripts yog ua los ntawm Parser.
- Optimizer. Txoj kev npaj kom muaj kev sib haum xeeb (DAG) raug xa mus rau qhov kev ua kom zoo tshaj plaws, uas ua rau kev ua kom zoo dua qub xws li kev kwv yees thiab kev thawb.
- Compiler.
- Execution cav.
- Atom.
- Tuple.
- Hnab.
- Daim ntawv qhia.

Dab tsi yog qhov txawv ntawm qhov xwm txheej thiab qhov xwm txheej hauv ITIL?
Qhov sib txawv ntawm cov xwm txheej thiab xwm txheej hauv ITIL Ib qho xwm txheej yog kev cuam tshuam uas tsis tau npaj tseg lossis txo qis hauv kev ua haujlwm ntawm IT kev pabcuam. Ib qho kev tshwm sim yog qhov hloov me ntsis hauv lub xeev ntawm cov kab ke lossis kev pabcuam hauv IT infrastructure
Dab tsi yog qhov txawv ntawm kev tswj qhov xwm txheej thiab kev tswj xyuas qhov xwm txheej loj?
Yog li MI yog hais txog kev lees paub tias qhov xwm txheej ib txwm muaj thiab Kev Tswj Xyuas Teeb Meem yuav tsis txiav nws. Ib qho xwm txheej loj yog kev tshaj tawm ntawm lub xeev xwm txheej ceev. Ib qho xwm txheej loj yog nruab nrab ntawm qhov xwm txheej ib txwm muaj thiab kev puas tsuaj (qhov twg IT Service Continuity Management txheej txheem pib)
Dab tsi yog cov txheej txheem ntaub ntawv yooj yim rau kev puas tsuaj thiab kev tsim txom?
Cov ntaub ntawv kaw lus yooj yim rau kev puas tsuaj, kev ua yuam kev thiab kev tsim txom vim nws yog ib hom ntawm cov ntaub ntawv digital. Nws kuj yog qhov yooj yim dua vim nws qhib rau leej twg. Hackers tuaj yeem tso tawm qhov tsis lees paub ntawm kev pabcuam (DoS) kev tawm tsam lossis nkag mus rau cov koom tes hauv tuam txhab, ua rau muaj kev cuam tshuam loj
Dab tsi yog cov ntaub ntawv yooj yim tsim los ua thiab nws ua tiav cov haujlwm no li cas?
Lub hom phiaj tseem ceeb tshaj plaws ntawm cov ntaub ntawv kaw lus yog tswj cov neeg siv cov ntaub ntawv. Qhov no suav nrog khaws cia, rov qab thiab kho cov ntaub ntawv. Qee lub tshuab ua ntaub ntawv lees txais cov ntaub ntawv khaws cia raws li cov kwj ntawm bytes uas tau sau thiab khaws cia kom zoo rau kev tshaj tawm
Dab tsi yog qhov dav thawj qhov kev tshawb nrhiav thiab qhov tob thawj qhov kev tshawb fawb?
BFS sawv rau Breadth First Search. DFS sawv cev rau Kev Tshawb Nrhiav Qhov tob. 2. BFS (Breadth First Search) siv Queue cov qauv ntaub ntawv los nrhiav txoj hauv kev luv tshaj. BFS tuaj yeem siv los nrhiav ib qhov chaw luv tshaj plaws hauv cov duab tsis hnyav, vim tias hauv BFS, peb mus txog qhov kawg uas muaj qhov tsawg kawg nkaus ntawm cov npoo los ntawm qhov chaw vertex
