• Real-World Examples: Hands-on examples and practical exercises were effective and well-received by many learners.
• Positive Impact: Some learners reported that the course significantly boosted their understanding of Hadoop after supplementing knowledge from various internet sources.
• Clear Instruction: The course was deemed clear enough, with one learner highlighting that if you start the course, you can't stop due to its engaging nature.

Cons:

• Unclear Naming Conventions: There was confusion regarding the naming of servers in the course, which made it difficult for learners to understand the roles of different nodes (e.g., "nn", "dm1", "vm1" instead of explicit naming like "Standby NameNode" or "DataNode").
• Lack of Explanation: Some learners felt that the instructor did not explain concepts sufficiently, leading to frustration and a sense that the course was incomplete.
• Outdated Content: The initial half of the course covered an outdated Hadoop version (1) and its ecosystem tools, which some learners found misleading as it did not align with current Hadoop versions (2).
• Insufficient Documentation: Learners suggested that the course could be improved with additional resources, such as PDFs or transcripts, to provide a clearer understanding of the lecture notes and step-by-step configurations.
• Inadequate Coverage of Advanced Topics: The practical portion of the course was found to lack depth in some areas, such as testing failover after setting up ZooKeeper, which could provide more comprehensive insights.
• Lack of Comprehensive Overview: The theoretical part of the course was considered apt and well-explained, but there was a demand for a broader overview to understand the context better.
• Rating Issues: One review indicated that the instructor's approach seemed to be based on learning from YouTube, which raised concerns about the depth and quality of instruction.

Course Structure and Organization

Pros:

• Well-Organized Theoretical Content: The theoretical aspects of the course were found to be well-presented and in line with expectations.

Cons:

• Confusing Server Names: The naming of servers within the course was a point of confusion, as it did not follow standard nomenclature for Hadoop components.
• Outdated Information: A significant portion of the course focused on an older version of Hadoop, which might mislead learners about current practices.
• Insufficient Practical Depth: While the practical examples were well-received, they could have benefited from a more in-depth exploration to fully cover all topics discussed.

Overall Assessment:

The course received mixed reviews, with positive feedback on its engaging content and practical exercises, but criticism regarding its theoretical depth and outdated information.
