The HDFS architecture consists of clusters, every of that's Accessed thru a single NameNode Software Program device established on a separate sySTEM to display and control the that cluster’s File device and consumer access mechanism. The different machines set up one example of DataNode to control cluster garage.

Because HDFS is written in Java, it has local help for Java utility Programming Interfaces (API) for Application Integration and Accessibility. It also may be accessed via preferred Web Browsers.
