Just because Hadoop's install process sucks that doesn't make you a bad sysadmin. Back in the day when we were building our kernels most of us weren't verifying download package sigs either. Containers aren't making us dumber either. A good sys admin just knows all of the working parts of a server and knows about the latest tools. The only way to get better is hands on practice. Try setting up your own Hadoop cluster from source and run a job through it, then put Hive on it, then attempt to containerize a node ... which not even work but learning why that won't work becomes useful knowledge. Just stumble through it and learn.
