Paritosh Ranjan updated MAHOUT-1091:
------------------------------------

Just tried out of curiosity. The patch contains the fix and a junit test
demonstrating the fix.
The math module's test cases pass after this fix. Have not checked the complete
build yet.
> Bug in SequentialAccessSparseVector full iteration

> The iterator for the SequentialAccessSparseVector doesn't return any items
> beyond the last non-zero. This breaks some stuff pretty massively, but
> hopefully doesn't break much user code since iterating through all elements
> of a sparse vector is a relatively rare thing to do.
