big data analysis recommendation system with hadoop framework

1. Scene:Now people are generating more and more data faster, machines are faster, so another way to process data is needed.The drive capacity increases, but the performance is not up, the solution is to divide the data into multiple hard disks, and then read at the same time.Problem:Hardware Issues-Replication data re

ToolsExplain why you should install VMware Tools.VMware Tools is an enhanced tool that comes with VMware virtual machines, equivalent to the enhancements in VirtualBox (if used with the VirtualBox virtual machine), only VMware Tools is installed to enable file sharing between host and virtual machines. It also supports the function of free dragging and dragging.VMware Tools Installation Steps:1. Start and enter the Linux system2. Virtual machine-install VMware Toolsor right-click the virtual ma

Bubble distribution chart (the larger the circle, the greater the importance), the top 10 big data tools that are most favored are Hadoop, Java, Spark, Hbase, Hive, Python, Linux, Strom, Shell programming, and MySQL. Both Hadoop and Spark are distributed parallel computing frameworks, which now seem to dominate

frameworks and multiple applications, such as the possibility of running spark on a cluster and running Hadoop, where data sharing between the two is now through HDFs. In other words, if the output of a spark application result is another MapReduce task input, the intermediate result must be written and read HDFs to achieve, we know that HDFs read and write first is a disk IO, in addition to its backup str
