Is Namenode machine same as DataNode machine as in terms of hardware in Hadoop?
Answer / Maheshwar Nath
No, Namenode and Datanode have different roles and requirements in terms of hardware in a Hadoop cluster. While Namenode is responsible for managing the file system namespace, storing metadata, and regulating access to data, it requires more resources such as high-speed storage, large memory, and a powerful CPU. On the other hand, Datanodes store the actual data blocks across the cluster and require high-capacity storage and network connectivity.
