FAQ
As far as I know, currently hadoop can only run under *nix like systems.
Correct me if I am wrong.
And if you want to run it under windows, you can try cygwin as the
environment.

Thanks

No, I hoped that it is not absolutely necessary for that kind of use. I am
not even issuing the "hadoop -jar" command, but it is pure "java -jar". It
is true though that my Ubuntu has a Hadoop set up, so maybe it is doing a
lot of magic behind my back.

I did not want to have my inexperienced Windows users to have to install
cygwin for just trying the package.

Thank you,
Mark

Hi, guys,

I want to give my users a sense of what my hadoop application can do,
and
I
am trying to make it run in Windows, with this command

java -jar dist\FreeEed.jar

This command runs my hadoop job locally, and it works in Linux.
However,
in
Windows I get the error listed below. Since I am running completely
locally,
I don't see why it is trying to do what it does. Is there a workaround?

Thank you,
Mark
