Hadoop on Windows

I have configured Hadoop for Windows Cygwin. I guess configuration is successful. But when I start dfs or mapred,
I get errors like

/usr/local/hadoop/bin/ line 30: pwd: Write error Bad file descriptor
/usr/local/hadoop/bin/ line 35: / No such file or directory
/usr/local/hadoop/bin/ line 38: / No such file or directory

Sometimes its getting started.

If I run bin/hadoop , it is hanging. It is not starting at all.

If I run bin/hadoop hadoop-test.jar, it says "Could be replicated to 0 nodes instead of 1"

I also see that

DFS used 100%
DFS remaining 0%

Is it causing any issue here?

I have more space left in my C drive but

I haven't tried this configuration myself ever [Windows + Cygwin + hadoop], but looks like $HADOOP_HOME is missing or not pointing to expected location [i.e. Hadoop installation dir].
I agree. Here's the link:
