Hadoop ->> 关于数据分割(Data Split)的思考 今天开始学习Hadoop这门热门的数据库技术。直接从被奉为Hadoop圣经的《Hadoop The Definitive Guide 4th Edition》入手。第一章作者写到一个关于分布型数据库系统在处理数据分割时的两种方法:1)按照某个单位(诸如年份或者数值范围);2)均匀分割所有数据到若干份(分布式计算机...

It is cited that the best way to test drive a prediction model is to run the process and compare the results with the model's prediction. However, when there's a lack of time and resources, data-splitting techniques can be used to...
