My small white one, recently is learning to big data Hadoop, before installing Hadoop to install the JDK, but I'm completely according to the book configuration after the JDK environment variables, "the source/etc/profile" command is always wrong, always show "comond not found", for which the great spirit support, (the picture is my JDK configuration)

CodePudding user response:

Do you perform the cat/etc/profile look at the results

CodePudding user response:

Back to the original poster, this is the terminal cource command error has nothing to do with the configuration path, please check the command or direct inspection Java javac can normal use

CodePudding user response:

First you need to download a decompression JDK, and set the JDK directory path, join the environment variables,
