Installation Help
Hi all,
I want to build a recommendation engine and think that Mahout is perfectly
suitable for this purpose.
The problem is that I am really new to mahout and can't even install it.
I am under windows vista and I have correctly installed maven. I use the
command mvn install
but the build fails in Mahout core because of test failures. (Failures:20,
Errors: 32)
I used both the trunk version and mahout 0.3 with the same problems.
Please give me a clue, I am trying for almost 2 days now..
Thanks in advance,
Lefteris

You sent a list of which tests failed, but you should include detailed
information on the failures from this file.

Thanks for your immediate reply,
I just set M MAVEN_OPTS=-Xmx512m but I still get the same error messages:

It works, but there aren't any production users that I have heard of and all
of the non-production users seem to use cygwin.

It's not Mahout, it's Hadoop really. Some of Mahout does not need
Hadoop. In fact most of the recommender engine code is not based on
Hadoop at the moment.
I don't know of anyone using Mahout with Windows though, no. I think
all the devs are Mac / Linux users.
If you get into Cygwin, pretty soon you will just buy a Mac for development :)

Yes of course, the build isn't failing, it's the tests that require Hadoop.
It's entirely legit to proceed this way if you don't actually need
Hadoop-related parts.

I did get it to work, but I had to:
mvn install -DskipTests
Once built, it seems to actually work fine. Or at least, the bits I
cared about (which was the recommendation engine). Of course, this is a
workaround rather than a solution. ;-) It may be the issue is something
to do with the testing rather than anything more deeply wrong, though.
Note I did this without cygwin (which I prefer to avoid...) and just at
the normal command shell.
Hope this helps,
Jonathan

Thanks again for the help,
I thought that mahout was working on windows..
Does no one else work with mahout on windows, or are Vista that cause the problem?
Anyway, I'll try the solution you propose. Hope it works!

There is a note in BuildingMahout page, but I think that the place is a
little
bit misleading. I would place Cygwin in the Prerequisites section of the
wiki page,
with an optional indication e.g. (Only on windows).

I suppose I don't need to install hadoop as well.. Just install Cygwin,

Re: Installation Help
Posted by Ken Krugler <kk...@transpac.com>.
If you're trying to run (versus develop) Hadoop on Windows, I think
you must use Cygwin.
So that same note should probably be added someplace on the Mahout
site, if it's not there already.
See http://hayesdavis.net/2008/06/14/running-hadoop-on-windows/ for
some good notes.

Re: Installation Help
Posted by Sean Owen <sr...@gmail.com>.
A-ha. It's trying to execute a command called chmod that is a standard
Unix/Linux/OS X command but not present on Windows.
I am not sure why Hadoop tries this on Windows though... surely it
supports Windows? I somehow think we've seen this before and I forget
what the story was.
It's not something to do with Mahout unfortunately.
One possible solution is to install Cygwin, which gives you a little
Unix-like environment on Windows. It has a chmod binary. Running via
Cygwin might work.

Nah in this case it's definitely 'chmod' to blame.

Quite likely the file separator or a space in a file path component.

Yeah that's still not quite showing the nature of the error.
Ted's saying that, for example, the output says that
TestFuzzyKmeansClustering failed. In target/surefire-reports, you'll
see a file with the output from this test. Could you for example find
the error in there and post it?
I'm guessing it is all due to some common cause related to the environment.

Any more information? at least we'd need to see some more error messages.
I have a first guess though, did you set MAVEN_OPTS=-Xmx512m ?
