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.
