----------------------------------

             Summary: Cannot create SparseVector with only one non-zero element.
                 Key: FLINK-1937
                 URL: https://issues.apache.org/jira/browse/FLINK-1937
             Project: Flink
          Issue Type: Bug
          Components: Machine Learning Library
            Reporter: Chiwan Park


I tried creating SparseVector with only one non-zero element. But I couldn't create it. Following code causes the problem.

{code}
val vec2 = SparseVector.fromCOO(3, (1, 1))
{code}

I got a compile error following:

{code:none}
Error:(60, 29) overloaded method value fromCOO with alternatives:
  (size: Int,entries: Iterable[(Int, Double)])org.apache.flink.ml.math.SparseVector <and>
  (size: Int,entries: (Int, Double)*)org.apache.flink.ml.math.SparseVector
 cannot be applied to (Int, (Int, Int))
    val vec2 = SparseVector.fromCOO(3, (1, 1))
                            ^
{code}
