Clients interact with HDFS using APIs such as Java's Hadoop FileSystem API, Python's PyHDFS, or the command-line interface (CLI) hdfs dfs. To write data, a client creates or appends to files by specifying the file path and data to be written. To read data, a client opens the file, sets a buffer size, and reads data from the DataNodes in blocks.
