Video: Dab tsi yog cov ntaub ntawv teeb tsa tseem ceeb uas yuav tsum tau hloov kho los teeb tsa hom kev faib tawm tag nrho ntawm Hadoop pawg?

Cov ntaub ntawv Configuration uas yuav tsum tau hloov kho los teeb ib hom kev faib tag nrho ntawm Hadoop yog:
- Hadoop-env.sh.
- Core-site. xml.
- Hdfs-site. xml.
- Mapred-site. xml.
- Masters.
- qhev.
Dhau li ntawd, cov ntaub ntawv teeb tsa tseem ceeb hauv Hadoop yog dab tsi?
Hadoop configuration yog tsav los ntawm ob hom ntawm cov ntaub ntawv tseem ceeb configuration:
- Nyeem-tsuas yog default configuration - src/core/core-default. xml, src/hdfs/hdfs-default. xml thiab src/mapred/mapred-default. xml.
- Site-specific configuration - conf/core-site. xml, conf/hdfs-site. xml thiab conf/mapred-site. xml.
Ib yam li ntawd, leej twg ntawm cov hauv qab no muaj kev teeb tsa rau HDFS daemons? xml muaj configuration kev teeb tsa ntawm HDFS daemons (i.e. NameNode, DataNode, Secondary NameNode). Nws kuj suav nrog qhov cuam tshuam rov ua dua thiab thaiv qhov loj ntawm HDFS.
Cov ntaub ntawv teeb tsa hauv Hadoop yog dab tsi?
Configuration Files yog cov cov ntaub ntawv uas yog nyob rau hauv lub extracted tar. gz ua ntaub ntawv hauv lwm yam / haoop ua / directory. Tag nrho Configuration Files hauv Hadoop muaj npe hauv qab no, 1) HADOOP -ENV.sh->>Nws qhia txog qhov hloov pauv ib puag ncig uas cuam tshuam rau JDK siv los ntawm Hadoop Daemon (ib / haoop ua ).
Cov ntaub ntawv twg cuam tshuam nrog cov teeb meem me me hauv Hadoop?
1) UAS ( Hadoop Archive) Cov ntaub ntawv tau qhia rau daws cov teeb meem me me . HAR tau qhia ib txheej rau saum HDFS , uas muab interface rau ntaub ntawv nkag mus. Siv Hadoop archive command, HAR cov ntaub ntawv yog tsim, uas khiav a MapRub hauj lwm los ntim cov cov ntaub ntawv tau archived rau hauv me me tus lej ntawm HDFS cov ntaub ntawv.

Dab tsi yog qhov txawv ntawm cov ntaub ntawv uas tau tsav thiab cov lus tseem ceeb uas tau tsav?
Qhov sib txawv ntawm Cov Ntsiab Lus Tsav Tsheb thiab Cov Ntaub Ntawv Tsav Tsheb: Cov Ntaub Ntawv Tsav Tsheb: Li no nws tau qhia kom khaws cov ntaub ntawv sim rau qee cov ntaub ntawv sab nraud sab nraud ntawm cov ntawv xeem. Cov Ntaub Ntawv Tsav Tsheb Kev Xeem Ua Haujlwm pab tus neeg siv cais cov ntawv xeem cov logic thiab cov ntaub ntawv xeem los ntawm ib leeg
Dab tsi yog qhov kev teeb tsa tseem ceeb uas cov neeg siv yuav tsum tau qhia kom khiav MapReduce txoj haujlwm?
Lub ntsiab configuration tsis uas cov neeg siv yuav tsum tau qhia nyob rau hauv "MapReduce" lub moj khaum yog: Txoj hauj lwm input qhov chaw nyob rau hauv cov ntaub ntawv faib. Txoj hauj lwm tso zis qhov chaw nyob rau hauv lub faib ntaub ntawv system. Input hom ntaub ntawv. Tso zis hom ntaub ntawv. Chav kawm uas muaj daim ntawv qhia ua haujlwm. Chav kawm uas muaj qhov txo qis ua haujlwm
Dab tsi yog tag nrho cov kab kev sib txuas lus uas xav tau rau kev sib txuas tag nrho rau taw tes network ntawm tsib lub khoos phis tawj rau lub khoos phis tawj?
Tus naj npawb ntawm cov kab sib txuas lus uas yuav tsum tau muaj rau kev sib txuas tag nrho ntawm qhov taw tes rau-taw tes ntawm yim lub khoos phis tawj yog nees nkaum yim. Ib tug tag nrho txuas cuaj lub computer network yuav tsum tau peb caug rau kab. Ib tug tag nrho txuas kaum lub computer network yuav tsum tau plaub caug tsib kab
Dab tsi yog tus lej ncaj qha uas yuav tsum raug tshem tawm ntawm cov ntaub ntawv tshawb fawb kom ua raws li kev siv cov ntaub ntawv txwv?
Cov ntaub ntawv qhia ncaj qha hauv qab no yuav tsum raug tshem tawm rau PHI kom tsim nyog raws li cov ntaub ntawv txwv: (1) Cov npe; (2) Cov ntaub ntawv chaw nyob xa ntawv, tsis yog lub nroog lossis nroog, xeev, thiab ZIP code; (3) xov tooj; (4) fax xov tooj; (5) email chaw nyob; (6) social security naj npawb; (7) cov ntaub ntawv kho mob; (8) kev npaj kho mob
Dab tsi VM Series koj yuav tsum xav txog yog tias koj xav tau cov ntawv thov host uas xav tau kev ua haujlwm siab IO rau cov ntaub ntawv tsis tu ncua?
Teb: VM series uas koj yuav tsum yog xav txog yog tias koj xav tau txais cov ntawv thov uas xav tau kev ua haujlwm siab rau cov ntaub ntawv tsis tu ncua yog VMware workstation, Oracle VM virtual box lossis Microsoft Azure suav. Cov khoom siv no muaj qhov yooj yim tshaj plaws ntawm kev ua haujlwm hosting
