  • Debugging Hadoop code is pain, but otherwise very nice class. I appreciate that it brings real-world examples and lets you try the code on live system, not only udacity coding platform.

    Can anyone tell what the benefit end users usually forum moderators will get from the extracted information in the final project?? i.e, Benefits of
    1-List of students per thread
    2-Finding Top Ten Tags.
    3- Student Timings i.e. at which they are most active
    4-Co-relation between question and answer.
  • This is a solid introduction to Hadoop and MapReduce concepts. The assignments are a good exercise in getting familiar with the basics. There's a lot that this course doesn't cover, but it's enough to get your feet wet with Hadoop and MapReduce concepts.
  • Very nice, introductory course; Video content is not much; very short and fast, but the exercise questions are well designed and illustrate some real-world applications of MapReduce
  • Ridiculously tiny videos, no detailed explanations, disappointed. Please add some more content and don't rush thorough them. Udacity could have done better

    This is good place to start with Hadoop HDFS filesystem and map reduce concepts. Good balance between theory and practice and approach is comfortable for novice.
