Thank you for the lecture. I am very satisfied with the fact that there is a lecture on big data. I hope many people, whether they are doing big data or not, will listen to it once. ^^ If you follow the instructions properly, from installing Hadoop to setting environment variables in Linux to installing and running Eclipse, everything will be fine. You just feed it everything. As the instructor said, those who have installed Hadoop directly must have used something like Cloudera, but it was good to install Hadoop from the beginning directly following the instructor. I repeated it several times to get used to it. Personally, what I regret is that it was great to install it on 1 Virtualbox in Ubuntu, but it would have been better if you had covered 1 namenode + 3 data nodes + HA configuration in CentOS. ㅎㅎ Aren't there any plans for a lecture on Spark? I will wait for the intermediate Hadoop lecture. Stay healthy and happy in Toronto~
Yes, thanks to Cho, I can't help but do the next intermediate lecture. I feel rewarded for making the lecture since you installed it so many times that you pointed out one error. I'm also going to make one namenode and several data nodes for the cloud environment, which is a regretful multi-node setup. No, if you upload it right away and various non-experts connect Hadoop from the beginning in detail, I hope that there will be many Hadoop expert teams in Korea. If you configure HA, you will probably be in the ranks of big data experts. I will try to pay more attention to the intermediate lecture so that even non-experts can follow it. However, since it takes time, please be patient and wait a little, and I will come back with a good lecture. Thank you again. I'm glad that you were very satisfied.
