Cracking the Hadoop woyambitsa zokambirana - Kodi muyenera kudziwa ndi kuchita chiyani?

Cracking Hadoop yopanga Interview

Apache Hadoop ndi ufulu, wotseguka; Mapulani a ndondomeko ya Java akukonzekera kuti asungidwe ndikusindikizidwa kukonzekera zambiri zomwe zimadziwika kuti Big Data. Zikhoza kuonedwa ngati chisankho chosankha kuti mupereke nthawi yowonjezera chidziwitso chokhudzidwa cha Hadoop ndi ntchito yake kotero kuti mukubala zipatso mukusokoneza zokambirana za Hadoop.

M'nkhaniyi tifunika kutengapo mbali pa gawo lalikulu lomwe mukuyenera kukumbukira pamene mukulakalaka kuti mukhale ndi ntchito yosangalatsa monga Hadoop.

Kodi Hadoop wogulitsa ali pafupi bwanji?

Ngati mwakhala watsopano ku phunziroli, tiyeni tiyambe ndi vuto la wogulitsa malonda m'malo mwa wogwiritsa ntchito Hadoop. Kwenikweni pali kusiyana kwakukulu pakati pa awiriwa ndi awiri omwe akuyang'anira kulemba zizindikiro ndi mapulogalamu. Kusiyanitsa kwakukulu ndikuti Hadoop wogwira ntchito amagwira ntchito pachigawo chachikulu cha Data. Zambirimbiri zimatanthauzira kumbiri yambiri ya chidziwitso chomwe chimapezeka mu petabytes, exabyte ndi zettabyte, zomwe zatha kupyolera mu mphamvu ya chidziwitso chokonzekera mapulogalamu.

Kodi Hadoop amathandiza motani?

Lingaliro lopambana kwambiri la Hadopop ndiloti lingathe kuchita zambiri zowonjezera. Amalonda ogwira ntchito zokopa alendo, umoyo wa inshuwalansi, thumba, kufalitsa, ndi zina zotero amafuna Hadoop kupanga, kuyang'anira, kuswa ndi kugwiritsira ntchito zambirimbiri zadzidzidzi.

Pa msinkhu wina, Hadoop ndiyenso kulekerera. Izi zikutanthauza kuti zimapangitsa kuti zinthu zisamayende bwino pamene dongosolo likupita mofulumira kudera linalake.

Malangizo ndi zidule kuti asokoneze kuyankhulana kwa Hadoop

Monga chofunikira choyamba muyenera kudziwa zambiri za machitidwe osiyanasiyana, mafotokozedwe, malingaliro, miyezo, ndi zina zotero zomwe zimapanga Hadoop. Chofunika kwambiri kuti mukhale ndi mphamvu yogwiritsira ntchito chidziwitsochi. Kuwonjezera apo, likulitsani luso lanu loyanjana ndi cholinga chomwe mungapititse patsogolo njira zanu. Khalani odziwa bwino malo anu ndikudzipangitsani nokha ndi zochitika zomwe mukuyembekezera panopa. Kumbukirani kuti palibe choloweza mmalo mwakhama ntchito, ndipo ndi zipangizo zolondola ndi ntchito yogwira ntchito, mutha kuzindikira momwe mungapezere malingaliro anu ntchito monga Hadoop wopanga mapulogalamu mu mgwirizano wapamwamba.
