Big data engineers should learn programming languages such as JAVA, Scala and Python. But these languages are interlinked. Mastering one programming language will make other languages easier to learn.

The learning of big data needs to master the following technologies: Hadoop, spark, storm and other core technologies. Basic technologies include data acquisition, data preprocessing, distributed storage, NoSQL database, data warehouse, machine learning, parallel computing, visualization and other technical categories and different technical levels.

Firstly, a general big data processing framework is given, which is mainly divided into several aspects: data acquisition and preprocessing, data storage, data cleaning, data query and analysis and data visualization.

Big data engineers can engage in the technical work of collecting, cleaning, analyzing, managing and mining a large amount of data, and using, managing, maintaining and serving these data.

The professional and technical level training examination for big data engineers is divided into three levels: primary, intermediate and advanced.
