I'll be clear, I've never used hadoop, so don't expect me to be right. In this thread: https://stackoverflow.com/questions/59536670/how-to-resolve-invalid-hadoop-yarn-home-error/65501695#65501695 I saw the comment: "The environment variables changed in Hadoop 3. Try again with actually using Hadoop 2.7.3 or find another tutorial (such as the official Apache one)" Using Hadoop 2.7.3 seemed to work for the OP. So make sure you're using the correct version of Hadoop, or using the correct env variables for the correct version. Sorry if I'm not of help. I only mentioned what I found from a quick web search, which I'm guessing you've akready done.
