Hadoop Distributed File System (HDFS) Block Replication – Big Data Analytics The design of HDFS is based on two types of nodes: one NameNode and one or more DataNodes. When a client wants to write data, it first communicates with the NameNode and requests to create a file. The NameNode determines how many blocks are
Components and Architecture Hadoop Distributed File System (HDFS) The design of the Hadoop Distributed File System (HDFS) is based on two types of nodes: a NameNode and multiple DataNodes. No data is actually stored on the NameNode. A single NameNode manages all the metadata needed to store and retrieve the actual data from the DataNodes.
