This is such a great lecture!!! I have a project launch at the end of the year, so unfortunately I don't think I'll be able to finish the entire lecture within the deadline... Is there any way to extend it..?

Not only is it an outdated version, but it's nearly impossible to practice due to the difficulty in identifying the causes of issues. The explanations are also too monotonous and difficult.

Experiencing the overall IT project greatly helped me decide which areas to study in the future. Thank you. Also, the troubleshooting article on the QnA board written by Big-D님 was very detailed, allowing me to set up the environment smoothly. Thank you very much. I have one request. The course period is almost over, and it overlaps with a certification exam schedule. If possible, could you please extend the course duration a little?

Project complete!! If you want to experience big data, this is a great course to take. It's not easy to experience the entire Hadoop ecosystem by following a curriculum, but this is currently the only lecture that provides that experience. Since it's a slightly older lecture, some of the references have been removed, but when you ask questions, you get answers within two days, so you can solve problems quickly. There are many similar questions in the community, so you can solve a lot of problems without even asking questions. Since resources aren't abundant, command execution often takes a long time. You'll also experience that the network environment is more unstable than you think. If you wait patiently, many things get resolved. You really have to wait a lot and often, more than you expect. Tip!! If the code you have to type is too long, take a screenshot and ask GPT to extract it; it's a bit more convenient. P.S. I was eager to see the results quickly and was impatient, so I asked a lot of questions rapidly, but thank you for answering each and every one of them so well.
