Lub Hortonworks Data Platform ( HDP ) yog kev ruaj ntseg-nplua nuj, kev lag luam-npaj, qhib qhov chaw Apache Hadoop kev faib tawm raws li qhov chaw nruab nrab ntawm architecture (YARN). HDP hais txog cov kev xav tau ntawm cov ntaub ntawv thaum so, siv zog rau cov neeg siv khoom siv sijhawm tiag tiag, thiab xa cov kev tshuaj ntsuam xyuas zoo uas pab ua kom muaj kev txiav txim siab thiab kev tsim kho tshiab.
Yog li ntawd, HDP thiab HDF yog dab tsi?
HDF - yog siv los lis cov ntaub ntawv hauv Motion. HDP - yog siv los tuav cov ntaub ntawv ntawm So. Tab sis HDP muaj cua daj cua dub (kev ua haujlwm ntawm lub sijhawm) thiab Kafka (kev xa xov xa tawm).
Puas yog Hortonworks HDP dawb? Hortonworks ua nyiaj los ntawm kev muag kev txhawb nqa, kev cob qhia thiab Kev Pabcuam Kev Ua Haujlwm (sib tham). Txij li thaum HDP yog Apache Licenced software, nws cov lej code kuj muaj nyob rau ntawm Github rau dawb (saib: Hortonworks Inc). Hortonworks Cheebtsam yog 100% Qhib Qhov Chaw, yuav tsum tsis muaj ntawv tso cai thiab yog dawb siv.
Tom qab ntawd, ib tus kuj yuav nug, HDF hauv Hadoop yog dab tsi?
Cloudera DataFlow (Ambari) Cloudera DataFlow (Ambari)-yav dhau los Hortonworks DataFlow ( HDF )-yog qhov ntsuas tau, lub sijhawm tiag tiag streaming analytics platform uas ingests, curates thiab tsom xam cov ntaub ntawv rau kev nkag siab tseem ceeb thiab kev txawj ntse tam sim ntawd.
Qhov txawv ntawm Hadoop thiab Apache Hadoop yog dab tsi?
Qhov sib txawv ntawm Apache Hadoop thiab Apache Spark Mapreduce. Nws kuj tseem ua cov ntaub ntawv tsim thiab tsis muaj qauv uas khaws cia hauv HDFS. Hadoop MapReduce yog tsim hauv a txoj hauv kev los ua cov ntim loj ntawm cov ntaub ntawv ntawm ib pawg ntawm cov khoom siv kho vajtse. MapReduce tuaj yeem ua cov ntaub ntawv hauv batch hom.

Secondary NameNode nyob rau hauv hadoop yog ib qho tshwj xeeb ntawm node nyob rau hauv HDFS pawg uas nws lub luag haujlwm tseem ceeb yog los saib xyuas cov ntaub ntawv kaw lus metadata tam sim no ntawm namenode. Nws tsis yog ib tug backup namenode. Nws tsuas yog checkpoints namenode cov ntaub ntawv system namespace
Acid hauv Hadoop yog dab tsi?
ACID sawv cev rau Atomicity, Consistency, Isolation, thiab Durability. Kev sib txuam ua kom ntseeg tau tias txhua qhov kev hloov pauv yuav coj cov ntaub ntawv los ntawm ib lub xeev siv tau mus rau lwm lub xeev. Kev cais tawm hais tias txhua qhov kev lag luam yuav tsum muaj kev ywj pheej ntawm ib leeg, piv txwv li ib qho kev lag luam yuav tsum tsis txhob cuam tshuam lwm tus
Yuav ua li cas yog ib tug txheej txheem nyob rau hauv lub operating system dab tsi yog ib tug xov nyob rau hauv lub operating system?
Ib tug txheej txheem, nyob rau hauv cov nqe lus yooj yim tshaj, yog ib tug executingprogram. Ib tug los yog ntau tshaj threads khiav nyob rau hauv cov ntsiab lus ntawm cov txheej txheem. Ib tug xov yog ib qho tseem ceeb chav tsev uas theoperating system faib lub sij hawm processor. Lub threadpool feem ntau yog siv los txo tus naj npawb ntawm cov ntaub ntawv thov thiab muab kev tswj hwm ntawm cov neeg ua haujlwm threads
