I've just painstakingly followed detailed instructions on how to install Hadoop on Windows 10. I have set the *_HOME and PATH environment variables correctly. Hadoop is in the path as when I enter hadoop it seems to start running, but gives me this message:
\Hadoop\hadoop-3.1.3\bin\ was unexpected at this time.
I have just followed the installation instructions carefully twice, and both installations were identical, so I didn't make a mistake on the second installation, I hope.
What could this error message mean, and what can I do about it?
