File not found exception running mahout-examples-0.4.job.jar

Hi,

I am trying to run Synthetic Control Data example for clustering. I am using
Cygwin on Windows. I have got the following error:

Wasim,

In that first error it says you don't have HADOOP_CONF_DIR set. This should be set as an enivironment variable to be the /conf/ subdirectory of the Hadoop home directory (explicitly named of course).  That could be the issue tho others can correct me if I'm wrong.

Wasim,

I'm a little confused because I'm not in a position to try this
myself, but if you have a pathname inside your own java code inside
that jar file, it needs to be a plain old windows pathname.

Perhaps some other windows user can chime in?

Re: File not found exception running mahout-examples-0.4.job.jar

Hi Benson,

I am a newbie to mahout and cygwin.

and you seemed to be pointing in the correct direction (in fact i knew that
is the issue, but have no solution). I am just running the k-means on
Synthetic Control Data from mahout wiki page, which looks for
examples-job.jar in my file system.

I have read about cygpath from here:
http://www.cygwin.com/cygwin-ug-net/using-utils.html but don't know how to
use it in my case i.e. how can i tell the following command to use the
output from cygpath.

$MAHOUT_HOME/bin/mahout
org.apache.mahout.clustering.syntheticcontrol.kmeans.Job

which looks for mahout-examples-0.4-job.jar in my file system. are
there any options which i can
specify?, like with java command i can specify the classpath.
for e.g. i can use cygpath in following way for specifying java class path:

javac -cp "$(cygpath -pw "$CLASSPATH")" hello.java

what are the options in my case of explicitly specifying the path of jar
file.

Java doesn't know about /cygdrive. It can't. It's not a cygwin app.
You need to use the output of cygpath -w.
