Detailed explanation-1: -HDFS is built using the Java language; any machine that supports Java can run the NameNode or the DataNode software. Usage of the highly portable Java language means that HDFS can be deployed on a wide range of machines. A typical deployment has a dedicated machine that runs only the NameNode software.
Detailed explanation-2: -Hadoop distributed file system. The Hadoop distributed file system (HDFS) is a distributed, scalable, and portable file system written in Java for the Hadoop framework.
Detailed explanation-3: -HDFS is a distributed file system that handles large data sets running on commodity hardware. It is used to scale a single Apache Hadoop cluster to hundreds (and even thousands) of nodes. HDFS is one of the major components of Apache Hadoop, the others being MapReduce and YARN.
Detailed explanation-4: -HDFS is implemented in programming language. Explanation: HDFS is implemented in Java and any computer which can run Java can host a NameNode/DataNode on it.
Detailed explanation-5: -HDFS exposes a file system namespace and allows user data to be stored in files. A file is split into one or more blocks, stored, and replicated in the slave nodes known as the DataNodes as shown in the section below. The data blocks are then distributed to the DataNode systems within the cluster.
