Day 2: Big Data Fundamentals & HDFS

Today I began with the basics of Big Data and Hadoop.

What I covered:

• Intro to Big Data (V's of Big Data)
• HDFS Architecture: how data is split and distributed across nodes
• Cloudera: a platform to work with Hadoop clusters

Key Concepts:

• Big Data isn't just about size — it's about complexity and speed
• HDFS uses NameNodes and DataNodes to manage distributed storage
• Cloudera makes setting up a Hadoop environment easier for developers

Next up: Linux & HDFS commands, and an intro to MapReduce!
