according to the query rookie tutorial, Hadoop is an open source distributed computing and storage framework developed and maintained by Apache Foundation. Hadoop provides reliable and scalable application-layer computing and storage support for huge computer clusters. It allows distributed processing of large data sets across computer clusters using a simple programming model, and supports expansion from a single computer to thousands of computers. Hadoop initialization depends on how you use Hadoop, not every time. If you run Hadoop in local mode, you need to initialize the Hadoop environment every time, including configuration files, directory structure, startup scripts, etc. If you are running Hadoop in pseudo-distributed mode or fully distributed mode, you only need to initialize it when you deploy Hadoop for the first time, and then you can start and stop the Hadoop cluster directly.
