Hello,
I have Hadoop cluster on which Hadoop 0.20.2 is installed. Is there a
way to use Mahout 0.9 on that cluster?
I understand that Mahout 0.9 is based on Hadoop 1.2.1, but I have this
constraint, so I cannot install another version of Hadoop on it.
Thanks,
Marko
Hi Marko,
You can configure Mahout 0.9 over Hadoop 0.20.2 but the Hadoop dependencies
might lead to failure quite a few time. One example, If I remember
correctly is that Hadoop 0.20.2 doesn't have MultipleInputs which is
required by a few algorithms of Mahout 0.9.

Hi Chandramani,
Thank you very much for your answer.
Can you please explain how can I do the configuration?
And also, in which amount can expect failures? I'm currently using
clustering algorithms, concretely Streaming K Means, do you perhaps
have any experience with it, should I expect
Hi Marko,
Nothing special needs to be done to get Mahout 0.9 running on Mahout 0.2.
The steps are same as 1.2.1. You might refer to this link
http://chandramanitiwary.wordpress.com/2014/03/20/installing-apache-mahout-on-ubuntu/
and there are other good links to for the same.
I don't remember the
Hi Chandramani,
Thanks, I'll try it. And thanks for your post, it is good. I hope that
sanity check will be enough for the cause.
Can you please tell me how can I deploy with Hadoop 0.20.2? I have
tried my approach locally, that is, I downloaded Mahout, got Hadoop
1.2.1 with it, and
Hi Suneel, Are you saying that if Mahout is forked from github here (
https://github.com/apache/mahout), will it work on Hadoop 2.x?

Hi,
I have tried to run spectral clustering example
http://mahout.apache.org/users/clustering/spectral-clustering.html and
got the following error:
Exception in thread main java.io.FileNotFoundException: No such file
or directory
Yes and it should be compiled with Hadoop2 Profile (I am assuming that
should be the default).

Hello,
Does anyone know whether it is possible to upgrade the version of lucene that
mahout's lucene.vector and luecene2seq functions are compatible with? Currently
they require lucene 4.6.1 indexes but this version is already quite dated...
Kind regards,
Tom
Yes it should be possible, and we have been upgrading to the latest and
greatest Lucene versions at the point of Release and may be a trivial
change.
Just gotta replace all references in the code for 'Version_46' with
'Version_Latest'.
Also Lucene = 4.7 mandate Java 1.7.
