Joseph K. Bradley updated SPARK-7511:
-------------------------------------
Assignee: Holden Karau
> PySpark ML seed Param should be varied per class
> ------------------------------------------------
>
> Key: SPARK-7511
> URL: https://issues.apache.org/jira/browse/SPARK-7511
> Project: Spark
> Issue Type: Improvement
> Components: ML, PySpark
> Reporter: Joseph K. Bradley
> Assignee: Holden Karau
> Priority: Minor
> Fix For: 1.4.0
>
>
> Currently, Scala's HasSeed mix-in uses a random Long as the default value for
> seed. Python uses 42. After discussions, we've decided to use a seed which
> varies based on the class name, but which is fixed instead of random. This
> will make behavior reproducible, rather than random, by default. Users will
> still be able to change the random seed.
> The default seed should be produced via some hash of the class name.
> Scala's seed will be fixed in a separate patch.
