using HBase matrices/vectors from Mahout

[Allen Day <al...@gmail.com>]

Hi,

I'm writing some adapter classes that allow HBase tables and rows to
be used from Mahout.  I have a working HBase row / vector adapter
written, and now going to do another for table / matrix.  I'd like to
contribute this to Mahout.  A couple of questions:

* what package should this code be in?  is org.apache.mahout.matrix right?
* when I prepare my patch for JIRA, where should I put the classes i
the directory hierarchy?  these classes will introduce dependency on
HBase, so is contrib or examples the right place?
* best way to name?  I'm currently calling these as HBaseVector
extends SparseVector, will do similar with the matrix class.

Thanks.

That all sounds about right.

This has nothing to do with hama, does it?

Do you have a way to consider an hbase query as a matrix?
