[jira] [Created] (MAHOUT-1882) SequentialAccessSparseVector inerateNonZeros is incorrect.

Andrew Palumbo created MAHOUT-1882:
--------------------------------------

             Summary: SequentialAccessSparseVector inerateNonZeros is incorrect.
                 Key: MAHOUT-1882
                 URL: https://issues.apache.org/jira/browse/MAHOUT-1882
             Project: Mahout
          Issue Type: Bug
          Components: Math
    Affects Versions: 0.12.2
            Reporter: Andrew Palumbo
             Fix For: 0.13.0


In {{SequentialAccessSparseVector}} a bug is noted.  When Cuonting Non-Zero elements {{NonDefaultIterator}} can, under certain circumstances give an incorrect iterator of size different from the actual non-zeroCounts.

{code}
 @Override
  public Iterator<Element> iterateNonZero() {

    // TODO: this is a bug, since nonDefaultIterator doesn't hold to non-zero contract.
    return new NonDefaultIterator();
  }
{code}
