II. Hadoop Ecosystem Overview

Hadoop is a distributed computing framework that allows efficient processing, storage, and analysis of large-scale data. The Hadoop ecosystem consists of various components that enable distributed data processing and analytics. These components are organized into layers, including storage, processing, and management.

The storage layer of the Hadoop ecosystem is provided by HDFS, which is a distributed file system that stores and manages large data sets across multiple nodes in a Hadoop cluster. HDFS provides high reliability, scalability, and fault tolerance for data storage.

The processing layer of the Hadoop ecosystem includes MapReduce, a distributed data processing framework used for large-scale data processing in Hadoop. It is designed to parallelize data processing across a cluster of nodes, enabling efficient data processing for large data sets. Additionally, Spark is another popular data processing framework that provides faster and more efficient data processing than MapReduce.

III. Hadoop Distributed File System (HDFS)

Hadoop Distributed File System (HDFS) is a distributed file system designed for storing and managing large data sets across multiple nodes in a Hadoop cluster. It provides high reliability, scalability, and fault tolerance for data storage. Some key features of HDFS include:

• Scalability: HDFS can store and manage data sets that are in the petabyte range, allowing organizations to efficiently store and manage large amounts of data.
• Fault tolerance: HDFS provides fault tolerance by replicating data across multiple nodes in a Hadoop cluster. In case of node failures, the system can still access the data by reading from the replicated copies.
• High availability: HDFS provides high availability by automatically detecting node failures and transferring the data to other nodes to ensure uninterrupted access to the data.

HDFS follows a master-slave architecture, where a single NameNode acts as the master node and manages the file system metadata, while multiple DataNodes act as slave nodes and store the actual data. The NameNode stores the file system metadata, including information about the file name, size, permissions, and locations of the data blocks. The DataNodes store the actual data in blocks.

When a client application wants to access data stored in HDFS, it communicates with the NameNode to locate the data blocks and then retrieves the data from the corresponding DataNodes. This allows for parallel access to data and efficient processing of large data sets.
