Error while installing Hadoop

[Nikhil Das Nomula]

I am trying to learn hadoop and I am following the installation steps on http://v-lad.org/Tutorials/Hadoop/12%20-%20format%20the%20namendoe.html. However I am getting the following error and I have no clues why is it not able to find PlatformName in the classpath. Also I am concerned about,"cygpath: can't convert empty path". Can anyone let me know what might be the reason that I am getting this error.

Thank you

Instead use the hdfs command for it.

After dealing with enough issues with cygwin, I installed ubuntu on my machine and was able to install and run hadoop on my machine without any issues. Here is the the tutorial that really helped me http://www.michael-noll.com/tutorials/running-hadoop-on-ubuntu-linux-single-node-cluster/
