This article is a brief introduction to Hadoop-related technical biosphere, while sharing a previously written practice tutorial that requires a person to take. Today, with cloud computing and big data, Hadoop and its related technologies play a very important role and are a technology platform that cannot be neglected in this era. 　　In fact, Hadoop is becoming a new generation of data processing platforms due to its open source, low-cost and unprecedented scalability. Hadoop is a set of distributed data processing framework based on Java language, from its historical development angle we can ...

The increasing volume of data and the increasing competitive pressures have allowed more and more enterprises to start thinking about how to tap the value of these data. Traditional BI systems, http://www.aliyun.com/zixun/aggregation/8302.html > Data warehouses and database systems do not handle this data well. 　　Reasons include: 1. The data volume is too large, the traditional database can not effectively store and maintain acceptable performance; 2. The newly generated data are often unstructured, while traditional parties ...

Open source Large data frame Apache Hadoop has become a fact standard for large data processing, but it is also almost synonymous with large numbers, although this is somewhat biased. 　　According to Gartner, the current market for Hadoop ecosystems is around $77 million trillion, which will grow rapidly to $813 million in 2016. But it's not easy to swim in the fast-growing blue sea of Hadoop, it's hard to develop large data infrastructure technology products, and it's hard to sell, specifically ...

When "Big Data" becomes a topic for people, Apache Hadoop is often followed. There is a good reason for this: Hadoop has a file system that is not afraid to import different data structures, and a massively parallel processing system (MPP) to quickly process large datasets. 　　Moreover, because Hadoop is built on commercial hardware and open source software, it has both a low and scalable advantage. These features make Hadoop architecture a very attractive technology for CIOs, especially in the face of the introduction of more differentiation, new ...

Let's not dwell on how much data a disk can hold or whether it will use Hadoop. 　　The real question about big data is how the business user will use Hadoop, how far our system can go on the intelligent path, and how we're going to make sure it's all under control. Over the past few years, big data technologies have come a long way, from an optimistic and positive buzzword to a difficult illness that people hate, and the focus shifted from sheer data to the pursuit of type and speed. The so-called "big Data" and its related technologies are experiencing ...

Large data as a concept in the IT field has been recognized by many people. As in many aspects of the IT field, new technologies were first used by large enterprises, and then in the late stages of the entire use curve, small and medium enterprises began to use it. Big data seems to have gone through the same process. As large data continues to evolve in the real world, it is gradually being applied to less large data elements. Most standards consider smaller datasets being handled by large data tools in a way that is specific to large data architectures. Still, there is a consensus that there will be more data, not less, in the future.

Storing them is a good choice when you need to work with a lot of data. An incredible discovery or future prediction will not come from unused data. Big data is a complex monster. Writing complex MapReduce programs in the Java programming language takes a lot of time, good resources and expertise, which is what most businesses don't have. 　　This is why building a database with tools such as Hive on Hadoop can be a powerful solution. Peter J Jamack is a ...

Within a few years, the NoSQL database has focused attention on performance, scalability, flexible patterns, and analytical capabilities. 　　Although relational databases are still a good choice for some use cases, like structural data and applications that require acid transactions, NoSQL is more advantageous in the following use cases: The data stored is essentially semi-structured or loosely-structured. 　　Requires a certain level of performance and scalability. 　　The application to access the data is consistent with the final consistency. Non-relational databases typically support the following features: Flexible ...
