Answer / Kavita Yadav
The NameNode is the master node in HDFS (Hadoop Distributed File System). It manages the file system namespace and coordinates data access across DataNodes. While it can theoretically run on commodity hardware, due to its critical role in maintaining consistency, it's often recommended to allocate more resources (like memory and storage) for the NameNode compared to other nodes.
