[jira] [Created] (SPARK-7678) Scala ML seed Param should vary per class

Joseph K. Bradley created SPARK-7678:
----------------------------------------

             Summary: Scala ML seed Param should vary per class
                 Key: SPARK-7678
                 URL: https://issues.apache.org/jira/browse/SPARK-7678
             Project: Spark
          Issue Type: Improvement
          Components: ML
            Reporter: Joseph K. Bradley
            Priority: Minor


In [SPARK-7511], we decided to use fixed random seeds per class, rather than generating a new random seed whenever an algorithm is instantiated.  We need to change this in Scala's HasSeed Param.

The default seed should be produced via some hash of the class name.
