---------------------------------------------------------------
1) I hiked the memory up to 2g, same result. Is it possible the option did not
transmit to the JVM that runs the job?
2) I did not have this problem under Eclipse.
In a separate investigation, running the _spectralkmeans_ mahout job gives the
attached command-line failure log attached as SpectralKMeans_fail_20110919.txt.
Yes, this is the 'get jars out to the hadoop executor' problem. The 'job' jar
does not seem to do what it needs. Again, note that one failure does not cause
the whole job to exit. I submit that there are multiple problems inside the
job, and somehow there is a problem where the main job configurations do not
get transmitted to a subsidiary executor.

> Project: Mahout
> Issue Type: Bug
> Components: Clustering
> Affects Versions: 0.4, 0.5
> Reporter: Jeff Eastman
> Assignee: Shannon Quinn
> Labels: clustering, k-means, visualization

> I've committed a new display example that attempts to push the standard
> mixture of models data set through spectral k-means. After some tweaking of
> configuration arguments and a bug fix in EigenCleanupJob it runs spectral
> k-means to completion. The display example is expecting 2-d clustered points
> and the example is producing 5-d points. Additional I/O work is needed before
> this will play with the rest of the clustering algorithms.
