Study Notes

Apache Hadoop Overview

The primary function of Apache Hadoop is to store and process large datasets in a distributed computing environment.

HDFS Components

HDFS (Hadoop Distributed File System) is responsible for storing and retrieving data in Apache Hadoop.
The purpose of HDFS is to provide a reliable, scalable, and fault-tolerant storage system for large datasets.

HDFS Components - NameNode

The NameNode is responsible for maintaining a directory hierarchy of the data stored in HDFS.
The NameNode keeps track of the file system namespace, including file blocks and their locations on the DataNodes.

YARN Components

YARN (Yet Another Resource Negotiator) is responsible for resource management and job scheduling in Apache Hadoop.
The ResourceManager is the component responsible for managing resources and scheduling jobs in YARN.

HDFS Components - Secondary NameNode

The Secondary NameNode is a standby NameNode that takes over in case the primary NameNode fails.
