Analysis of Cloud Computing Infrastructure Based on Hadoop

摘要: Hadoop is an open-source software platform which can achieve large-scale distributed computing,so it widely used in cloud computing.Starting from the file system architecture of Hadoop,we describe its core content four aspects data storage,distributed task assignment,distributed parallel computing and database,and discuss HDFS working principle,file operation process,as well as Map/Reduce principle computation procedure.The aim to make developers further understand implementing process architecture,and provide reference for application development under background.
