The client node is responsible for accepting user requests and providing a file system abstraction to the user application. It communicates with the name node to get the metadata about the files and communicates with the data node to read or write data. Therefore, the client node acts as the interface between the user application and the HDFS. Data node stores the actual data, name node stores the metadata information about the file system, and map node does not exist in HDFS.
