[jira] [Created] (SPARK-6150) Validate indices before constructing a SparseVector

Yu Ishikawa created SPARK-6150:
----------------------------------

             Summary: Validate indices before constructing a SparseVector
                 Key: SPARK-6150
                 URL: https://issues.apache.org/jira/browse/SPARK-6150
             Project: Spark
          Issue Type: Bug
          Components: MLlib
            Reporter: Yu Ishikawa
            Priority: Minor


We can set the invalid indices when constructing a SparseVector. We should validate the indices before the construction.

It should be invalid, but we can make a SparseVector with below. It is not until we access the value with the index that an exception is raised.

{code}
Vectors.sparse(4, Array(100), Array(1.0))
{code}
