> I actually stumbled on the fact that SSVD code doesn't have 'overwrite
> results' option. Which might not be not a big deal if it weren't for the fact
> that it also turns out to be the default behavior as well (i.e. by default it
> would overwrite target path if it already exists). Which promotes it to a
> verge of a bug.
> I think i need to attend to it by introducing overwrite option and disabling
> this by default. (i.e. by default it would fail if the output path already
> exists). I think this is consistent with some other CLI in Mahout I saw.
