What does hadoop mean?

Hadoop is a distributed system infrastructure developed by the Apache Foundation.

Users can develop distributed programs without understanding the underlying details of distribution.

Make full use of the power of clusters for high-speed computing and storage.

Hadoop implements a Distributed File System, one of its components is HDFS.

HDFS is highly fault-tolerant and designed to be deployed on low-cost hardware; and it provides high throughput to access application data, making it suitable for those with large data sets.

set) application.

Extended information: Advantages of Hadoop: 1. High reliability: Hadoop's ability to store and process data bit by bit is worthy of people's trust.

2. High scalability: Hadoop distributes data and completes computing tasks among available computer clusters. These clusters can be easily expanded to thousands of nodes.

3. Efficiency: Hadoop can dynamically move data between nodes and ensure the dynamic balance of each node, so the processing speed is very fast.

4. High fault tolerance: Hadoop can automatically save multiple copies of data and automatically redistribute failed tasks.

5. Low cost: Compared with all-in-one machines, commercial data warehouses, and data marts such as QlikView and Yonghong Z-Suite, hadoop is open source, so the software cost of the project will be greatly reduced.
