Sean Owen commented on MAHOUT-337:
----------------------------------
I could see it, OK. You'd need to fix the original problem then, which is that
two equal vectors have differing string representations. This cause some issue
for Pallavi. Nixing the string output solves that in a brute-force way... does
the Printable output not have the same issue? or we're saying not-a-bug, you
shouldn't compare serialized representations this way?
> Don't serialize cached length squared in JSON vector representation
