Unlike the DataNodes, a NameNode is a highly available server that manages the File System Namespace and maintains the metadata information. Therefore, NameNode requires higher RAM for storing the metadata information corresponding to the millions of HDFS files in the memory, whereas the DataNode needs to have a higher disk capacity for storing huge data sets.
