---------------------------------------
Summary: toString() method of SequentialAccessSparseVector has
excess comma at the end
Key: MAHOUT-1301
URL: https://issues.apache.org/jira/browse/MAHOUT-1301
Project: Mahout
Issue Type: Bug
Components: Math
Affects Versions: 0.8
Reporter: Alexander Senov
Priority: Trivial
Realization of SequentialAccessSparseVector toString() method had changed in
MAHOUT-1259 patch. Unfortunately, that patch introduced new bug: output of the
toString() method had been changed - extra comma added at the end of the string
Example:
Consider following sparse vector
{code:java}
Vector v = new SequentialAccessSparseVector(capacity);
v.set(1, 0.1);
v.set(3, 0.3);
{code}
In 0.7 v.toString() returns following string:
{code:java}
{1:0.1,3:0.3}
{code}
but in 0.8 it returns
{code:java}
{1:0.1,3:0.3,}
{code}
As you can see, there is extra comma at the end of the string.
