    we use mahout-math in a scalding for similar purposes. see here:

    the main motivation for us was the sparse vectors, and some handy routines 
in mahout for vectorization of input documents. 
    
    however if mahout-math is no longer actively maintained then that's 
worrisome. i wasnt aware of that.
    
    i ended up on this pull request because i was just considering using mahout 
vectors in spark for a project... guess i will just follow this thread now and 
sit tight :)
