🟢We're back with the second session of the Big Data tutorial series! Learn all about HDFS from Rajan Chhetri, our Big Data expert!

Unlock the fundamentals of big data with our comprehensive guide on Hadoop Distributed File System (HDFS) brought to you by upGrad. This What is HDFS tutorial is perfect for beginners eager to dive into the world of big data storage and processing.

*What is HDFS?
Hadoop Distributed File System (HDFS) is the primary storage system used by Hadoop applications. It is designed to store and manage large datasets across multiple machines in a distributed environment. HDFS ensures data reliability and fault tolerance, making it ideal for big data applications.

*HDFS Architecture:
We'll explore the core components of HDFS architecture, including:
- NameNode: The master server that manages the file system metadata and regulates access to files by clients.
- DataNodes: The worker nodes that store actual data. They handle data storage, retrieval, and replication under the guidance of the NameNode.
- Secondary NameNode: It performs periodic checkpoints and helps in reducing the workload of the primary NameNode, enhancing system efficiency.

*How HDFS Works:
Understand the workflow of HDFS, including how it:
- Splits large files into smaller blocks and distributes them across DataNodes.
- Maintains multiple replicas of each data block to ensure data availability and fault tolerance.
- Manages file read/write operations to ensure data consistency and integrity.

*Setting Up HDFS:
Get a step-by-step walkthrough of setting up HDFS in your Hadoop environment. Learn how to:
- Install Hadoop and configure HDFS.
- Format the NameNode.
- Start HDFS daemons and verify their status.

*Practical Applications:
Discover the real-world applications of HDFS in various industries such as:
- Data analytics
- Machine learning
- Enterprise data warehousing
- Stream processing

Conclude with expert tips and best practices for optimizing HDFS performance, managing large datasets, and ensuring data security.
