Szymon Chojnacki commented on MAHOUT-588:
-----------------------------------------
seq2sparse_small_fail does not have detailed info why a job did not succeed,
e.g.
2011-01-30 01:25:55,726 INFO org.apache.hadoop.mapred.JobClient (main): Task Id
: attempt_201101300001_0003_m_000159_0, Status : FAILED
I get such info locally, maybe changing mapred.child.java.opts parameter in
conf/mapred-site.xml can help, I have:
<property>
<name>mapred.child.java.opts</name>
<value>-Xmx2000M -XX:-HeapDumpOnOutOfMemoryError</value>
</property>
> Benchmark Mahout's clustering performance on EC2 and publish the results

> Project: Mahout
> Issue Type: Task
> Reporter: Grant Ingersoll
> Attachments: SequenceFilesFromMailArchives.java,

> seq2sparse_xlarge_ok.log

> 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.
