The usage of big data has gradually increased Several major big data analytics vendors entering the magic quadrant this time are Cloudera, Hortonworks, and MapR, and existing customers of these big data architecture manufacturers promise to increase their investment. For example, Gartner mentioned that most existing Cloudera customers intend to purchase more licenses, products, and functions in the next 12 months.

In today's enterprises, 80% of the data is unstructured data, which increases by 60% every year. Big Data will challenge enterprises' Storage Architecture and Data center infrastructure. It will also trigger a chain reaction to applications such as data warehouse, data mining, business intelligence, and cloud computing. In the future, enterprises will use more TB-level (1 TB = 1024 GB) data sets for business intelligence and business analysis. By 2020, global data usage is expected to surge by 4

I. Introduction to the Hadoop releaseThere are many Hadoop distributions available, with Intel distributions, Huawei Distributions, Cloudera Distributions (CDH), hortonworks versions, and so on, all of which are based on Apache Hadoop, and there are so many versions is due to Apache Hadoop's Open source agreement: Anyone can modify it and publish/sell it as an open source or commercial product.Currently, there are three main versions of Hadoop that ar
