Buku Lathunthu lothandizira Hadoop

Osapitirira zaka 5, Hadoop adzakhala yekha omwe amachititsa mbali yaikulu ya deta ya dziko lapansi. Makina atsopanowa ndi otentha, ndipo makampani ali osowa kwambiri omwe akufuna kukhala ndi Hadoop certification.

Ndondomeko ya Hadoop

Pulogalamu ya Java ya Hadoop imangokhala yotseguka ndipo imapangidwira kukonzekera zikuluzikulu komanso zopambana zomwe zimapezeka mkati mwa chikhalidwe cha PC. Monga Hadoop amagwiritsa ntchito ma servers odzichepetsa pokonzekera deta, makampani ndi mabungwe onga ndi otsamira ku chitsanzo kuti mtengo wake ukhale woyenera. Zopindulitsa zosiyana za pulojekitiyi zikuphatikizapo kukonzekera kwa mitundu yosiyanasiyana ya deta yogawidwa mosiyanasiyana, kukwanitsa, kukhathamiritsa dera la deta, chithandizo cha zigawo zazikuluzikulu, ndi kayendetsedwe ka zowonongeka mwa njira yomweyo.

Zigawo zazikuru za 2 za bungwe la Hadoop zimaphatikizapo MapReduce ndi HDFS. Dongosolo la Hadoop lirilonse lirilonse la deta likulowa muzitsulo zing'onozing'ono za deta kapena mapulaneti ndipo mapaketi a deta achotsedwa mkati mwa malo osiyana ndi osiyanasiyana, malowa amakhala mkati mwa magulu. Hadoop ndi nthawi yodziwikiratu komanso nthawi yake yochotsera deta yaikulu kapena yaying'ono pamakumbukiro a bwalo ndiloling'ono kwambiri. Hadoop imanenanso zonse zomwe zimagwiritsidwa ntchito pa makina osiyana omwe ali mkati mwa gululo ndipo zolembedwazo zimakhala zofanana ndi zomwe zimachitika. Pamene zolemba zosiyanasiyana zingatheke mosavuta panthawi imodzimodzi, nthawi yosamalira deta imachepetsedwa.

Choncho, Hadoop certification ikuwonetsa kuti mungagwiritse ntchito ndondomeko yoyendetsera deta kuti muwonjezere zokolola za bungwe. Makampani lero akufufuza nthawi zonse a Hadoop certification holders, zomwe zikuwonetsa kudalirika ndi luso lomwe muli nalo lokonzekera kutenga ntchito zokhudzana ndi Big Data kusamalira.

Nchifukwa chiyani Hadoop Certification ya Ntchito Yanu?

Hadoop ndi njira yatsopano yogwiritsira ntchito deta yambiri, ndipo Hadoop imatsimikizira akatswiri akufunikira ku inshuwalansi, chithandizo chaumoyo, ndalama, malonda, mphamvu ndi magulu osiyanasiyana a malonda ndi zowonongeka. Kukhazikitsidwa kwa Hadoop kwakhala kopambana kwambiri ndipo akatswiri ambiri a IT asintha njira yawo ya ntchito kuti athe kugwiritsa ntchito zipangizo zamakono. Hadoop tsopano ikukondedwa pa Mainframe, Java, ndi Data yosungiramo zinthu komanso m'tsogolo muno, chikhazikitso chatsopano chidzakhala chiganizo chachikulu pa kusanthula deta ndikukonzekera.

Ubwino wa Hadoop Training

Maphunziro a Hadoop ndi certification ali ndi ubwino wosiyanasiyana kwa akatswiri onse odziwa ntchito zapamwamba ndi zowonjezera.

  • Chizindikiritsochi chiri chofunika ndipo makampani akufufuza mwachangu ofunafuna omwe ali ndi udindo wovomerezeka wa Hadoop ndi luso.
  • The Hadoop certification imapereka kwa inu onse malipiro ndi kukwera phiri, ndipo mukhoza kupeza zambiri kuposa ena atatha kupitiliza maphunzirowo bwinobwino.
  • Zatsopano zomwe zimapangidwa ku Hadoop ndi chikhalidwe zimatha kupereka chizindikiritso ndikupeza zomwe zimatengera ndi chidziwitso chothandizira kukhazikitsidwa ndi kukhazikitsidwa kwake.
  • Pamene maphunziro ndi nthawi yeniyeni ndikukulimbikitsani kuthana ndi zochitika zenizeni za dziko ndi deta, chizindikiritsochi chimasonyeza kuti muli ndi manja omwe mukugwira nawo mbali zokhumba.
  • Amasonyeza kuti mumadziwa zonse zamakono zamakono ndipo mukhoza kuthandiza ena kuphunzitsidwa ndi kampani.

Gawo ndi siteji malangizo okonzekera Hadoop Certification

The Hadoop certification maphunziro amaphatikizapo maola ochepa a 30 pa intaneti ndikukhala maphunziro omwe apangidwa ndi ophunzitsidwa, ovomerezedwa ndi omatsimikizira aphunzitsi. Mukhoza kupeza kusintha kwa nthawi yomwe mumafuna kuphunzira maphunziro. Mudzafunikanso kutenga ntchitoyi, ndipo vuto lenileni la moyo limasonyeza kuti mukuthandizidwa kuti mukhale nawo pa ntchito yeniyeni yadziko. Pali mavuto ochepa omwe amafunika kuti aphunzire maphunzirowa, monga mtsogoleri wotsogoleredwa pa Intaneti akukupatsani inu 24 * 7 yopezeka pa intaneti ya bolster yomwe imabwera kuchokera kwa akatswiri. Mumakambirananso zokambirana kumene mungasangalale ndi kutsogozedwa komwe mumagawana ndikugawana nzeru zanu pamene mukukumana ndi ena. Kuwonjezera pa ubwino umenewu komanso maphunziro opindula, mumaphunziranso zochitika zomwe mukuphunzira, zomwe zimakulitsa maluso anu ndi luso lanu ndipo zimakupangitsani kuti mukhale osagwirizana ndi kusintha kwaposachedwa ndi kusintha kwa Hadoop.

Hadoop Curriculum

Nkhani zazikulu ndi mitu yopezeka ndi Hadoop certification maphunziro ndi awa:

  • Hadoop ndi Big Data zomangamanga
  • HDFS
  • MapuPewani dongosolo
  • Mimba
  • Nkhumba
  • HBase ndi Hive
  • HBase Yopambana
  • Hadoop ndi Oozie akuwonjezera
  • Kusintha ndi kufalitsa deta pogwiritsa ntchito Apache Spark

Pulogalamu yophunzitsa pa Intaneti idzakhazikitsa makina omwe ali mkati mwa PC yanu ndipo idzakupatsani mwayi wopezeka. LMS kapena Learning Management System idzakhala ndi mauthenga onse okhudzana ndi kulandila ndi kufalitsa omwe muyenera kuwona maphunzirowo. Maphunziro a phunziroli adzafika kwa inu kumapeto kwa maphunzirowo ndipo mudzakhala mukugwiritsa ntchito mapulani a mchenga monga HIV, PIG, MapReduce ndi HBase pochita ma analytics pa Big Data mu nthawi yeniyeni. Maphunzirowa ndi makampani - makamaka ndi ofanana ndi malo amalonda monga media, ndege, malonda, ndalama, ndi ena.

Pamene gawo lonse la kuphunzitsa ndi maphunziro lichotsedwa mkati mwa LMS, simungamve kutayika kwa maphunziro aliwonse ndipo mungathe kuwapeza nthawi iliyonse yomwe mukufuna. Kupatula ku LMS, magawo a moyo amachitiranso maphunzirowo pamagulu osiyanasiyana ndipo mukhoza kuphunzira nkhani zomwe mwaphonya pa adilesi kapena sukuluyi.

Kodi ndi zofunika zotani kwa Hadoop Certification?

Ngakhale kulibe zofunikira pakusankha kwa Hadoop certification, ndi bwino kuti mutha kukhala ndi mwayi wokhudzana ndi SL ndi Core Java. Mungaphunzire makhalidwe a Java kapena mukhoza kuwatsitsimula mwa kulowera njira ina yochepa.

Mukufunikira PC ndi osachepera 4 GB ya RAM, pamodzi ndi pulosesa ya i3 (kapena yoposa) kuti mulowe nawo pa Intaneti ndikuphunzira bwino. Ngati simukukwanitsa kukwaniritsa zofunikira zina, mukhoza kupatsidwanso kutali ndi gulu la Hadoop ndi maziko anu ovomerezeka.

Nchifukwa chiyani Hadoop Training ikuyenera pa Ntchito Yanu?

Makampani abwino kwambiri a mayiko, kuphatikizapo MNCs a kukula kwakukulu amafunikira akatswiri a COMPASS omwe angathe kusunga deta zambiri zomwe ayenera kugwiritsa ntchito kapena kusunga. Kukula kwa deta kungakhale kotopetsa kwambiri ndikuchotseratu zenizeni komanso zolondola zomwe zingakhale ntchito yovuta kwambiri. Anthu omwe adutsa vumbulutso la Hadoop mokwanira akhoza kukwaniritsa cholingacho mosavuta. Pamene dongosolo la Hadoop likupeza mpata kuti ukhale wofunikira komanso wodalirika sabata iliyonse ndi mwezi, chizindikiritso cha malowa chingakuwonetseni kuti mupindule kwambiri muzochita zapadera.

Malo ophunzitsira a Hadoop akuzungulira kukupatsani nonsenu Big Data kukonzekera luso ndipo cholinga chanu ndikutsimikizira Big Data dokotala. Manja oterewa akugwirizana ndi njira zomwe amavomereza ndi chilengedwe cha MapReduce, HDFS, HBase, Nkhumba, Hive, Sqoop, Oozie ndi zina zomangamanga. Maphunziro a Hadoop amakupatsani maluso ofunikira komanso kuphunzira m'madera monga:

  • Mitundu yosiyanasiyana ya deta
  • Kumvetsetsa kwa zomangamanga za Hadoop 2x
  • Kukhazikitsa gulu la Hadoop ndikupanga mapulogalamu ochepetsa mapu a mapu
  • Kuyambira pa data analytics pogwiritsira ntchito Mbira, Nkhumba, ndi YARN pakati pa mapangidwe osiyanasiyana ndi zitsanzo
  • Kuphatikizidwa kwa Mapu Kuchepetsa ndi kukhazikitsidwa kwa H Base
  • Kupanga ntchito pogwiritsa ntchito Oozie
  • Kugwira ntchito kumvetsa RDD kwa Spark ndi dongosolo lonse lachilengedwe
  • Kuwombera pa moyo weniweni ukupitirira ndikufufuza za analytics zokhudzana ndi deta yaikulu.

Kafukufuku wam'mbuyowo akuwonetsanso kuti kufunika kwa Hadoop monga Big Data handling framework akungowonjezereka posachedwa. Malipoti akunena kuti msika wa Hadoop udzakhala pafupi $ 99.31 biliyoni usanafike chaka cha 2022, ndipo udzakhala ndi chiwerengero cha 42.1 posachedwa.

Kuphunzira deta yaikulu ndi Hadoop kumapanga zowonjezereka komanso ophunzitsidwa bwino a IT. Akatswiri, mapulani, kuyesa, BI, DDW, ndi akatswiri a ETL onse angathe kuphunzira kuwonjezera malingaliro awo ndikuwagwiritsa ntchito pakugwira ntchito zambiri.

Hadoop Certification Process

Mbuye wa webusaiti ya pa Intaneti ya Hadoop adzayang'ana ntchito yanu yomalizira, ndipo mwangozi mutadutsa chivomerezocho, mudzapatsidwa chikalata cha Big Data ndi Hadoop. Chivomerezocho chimayamikira kuvomereza ndi kuvomereza kwakukulu. Makampani ambiri otsogolera ndi MNCs ndi omwe amagwira nawo maphunziro otchuka otchedwa online coaching and training, ndipo awa ndi Wipro, Nokia, Cisco, Ford, IBM ndi zina zotero. Mukhoza kutsimikiziranso kuti chizindikiritso chanu ndi chowonadi ndipo chidzakupatsani ntchito yodziwika bwino komanso malipiro.

The Hadoop certification idzakupangitsani inu kukhala oyenerera ndalama za $ 98 k kapena pang'onopang'ono ndipo muli ndi chidziwitso, malipiro akuwonjezeka kwambiri. Pali zochuluka zopezera deta yaikulu za 4.4 miliyoni kwa inu tsopano, ndipo zitseko zotseguka zikuwonjezeka pa mlingo wa 12%. Okonza Hadoop ndiwo abwino kwambiri omwe amayang'ana pambuyo pa deta kumangidwa masiku ano, ndipo mukhoza kuthandizana ndi gululi tsopano kuti mufufuze za skylines yatsopano.
