Project complete!! If you want to experience big data, this course is really good to take at least once. It's not easy to experience the whole of Hadoop by following the curriculum, but this is currently the only course that provides that experience. Since it's a slightly older course, there are many cases where references have been removed, but if you ask a question, you get a response within two days, so it's quickly resolved. There are many similar questions in the community, so you can solve a lot of problems just by looking them up without even having to ask. Resources are not abundant, so command execution often takes a long time. You also experience that the network environment is more unstable than you think. If you wait patiently, many problems get solved. You have to wait really often and a lot more than you think. Tip!! If the code you have to type is too long, take a screenshot and ask GPT to extract it, it's a little easier. P.S. I wanted to see the results quickly and I was impatient, so I sometimes asked a lot of questions in a rush, but thank you for answering each one so well.
