Hadoop yog tus pheej yig

Tus nqi ib terabyte los siv a Hadoop pawg yog pheej yig dua tshaj tus nqi ib-terabyte los teeb tsa ib daim kab xev thaub qab. Pom zoo, a Hadoop system raug nqi ntau dua rau kev khiav lag luam, vim hais tias lub disk drives tuav cov ntaub ntawv yog tag nrho hauv online thiab powered, tsis zoo li daim kab xev drives.

Ua li no, yog Hadoop tus nqi zoo?

Hadoop muaj scalable, nqi - siv tau thiab muaj kev daws teeb meem rau cov ntaub ntawv loj thiab kev ua haujlwm. Kev siv cov txheej txheem lub cev tsis muaj tswv zoo heev txo qhov kev vam khom rau kev siv tshuab. Nws kuj tseem muaj peev xwm ua kom muaj peev xwm ua kom muaj zog thaum siv rau ntawm cov tshuab virtual lossis txawm nyob hauv IAAS huab.

Tsis tas li ntawd, vim li cas lub txim taws zoo dua Hadoop? Apache Teeb – Teeb yog xob laim ceev cluster xam cov cuab yeej. Apache Teeb khiav daim ntawv thov mus txog 100x sai dua hauv lub cim xeeb thiab 10x sai dua ntawm disk tshaj Hadoop .

Qhov no txhais tau tias node nqi yog kwv yees li $1,000 txog $2,000 ib TB. HDFS tsis muaj kev txwv lub cev ntawm cov ntaub ntawv loj.

Vim li cas Hadoop sai dua?

Qhov laj thawj yog vim li cas Spark sai dua tshaj Hadoop yog tias Spark ua txhua yam hauv nco. Nws tseem tuaj yeem siv lub disk rau cov ntaub ntawv uas tsis haum rau hauv lub cim xeeb.
