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

             Summary: PythonMLlibAPI trainGaussianMixture seed should use Java type
                 Key: SPARK-5609
                 URL: https://issues.apache.org/jira/browse/SPARK-5609
             Project: Spark
          Issue Type: Bug
          Components: MLlib, PySpark
    Affects Versions: 1.3.0
            Reporter: Joseph K. Bradley
            Priority: Trivial


trainGaussianMixture takes parameter seed of type scala.Long but should take java.lang.Long.
Otherwise, the test for whether seed is null (None in Python) will be ineffective.  See compilation warning:
{code}
[warn] /Users/josephkb/spark/mllib/src/main/scala/org/apache/spark/mllib/api/python/PythonMLLibAPI.scala:304: comparing values of types Long and Null using `!=' will always yield true
[warn]     if (seed != null) gmmAlg.setSeed(seed)
[warn]              ^
{code}
