Shannon Quinn commented on MAHOUT-524:
--------------------------------------
I've been tooling around with this code for a few hours now and cannot figure
out where the pesky "/data" is being appended to the overall path...or why the
second Path that Lance mentioned isn't what is actually being used. It has to
be somewhere in the Lanczos solver code (filtering into the
DistributedRowMatrix and its TimesSquaredJob, as the latter is what is actually
causing the exception), but in all my searching and println()-ing of paths I
can't seem to find it.
I'm going to keep looking, but any help in finding this bug would be greatly
appreciated.

> 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.
