Szymon Chojnacki commented on MAHOUT-588:
-----------------------------------------
Finally I managed to go through all steps (until ClusterDisplay) with the local
development environment. In order to avoid OutOfMemory I changed
/conf/mapred-site.xml and added:
<parameter>
<name>mapred.child.java.opts</name>
<value>-Xmx5000M </value>
</parameter>
It enabled to go reach the end of the processing, but there were a few 600s
timeout problems and a few jobs were killed. In order to avoid this, I also had
to add
<parameter>
<name>mapred.task.timeout</name>
<value>0</value>
</parameter>
I'll describe in detail all the steps (might be useful for EC2) and switch to
process in the AWS. I'll also try to figure out the minimum requirements for
-Xmx.

> For Taming Text, I've commissioned some benchmarking work on Mahout's
> clustering algorithms. I've asked the two doing the project to do all the
> work in the open here. The goal is to use a publicly reusable dataset (for
> now, the ASF mail archives, assuming it is big enough) and run on EC2 and
> make all resources available so others can reproduce/improve.
> I'd like to add the setup code to utils (although it could possibly be done
> as a Vectorizer) and the publication of the results will be put up on the
> Wiki as well as in the book. This issue is to track the patches, etc.
