Joseph K. Bradley commented on SPARK-7653:
------------------------------------------
Update: We should not really test for trait HasSeed since we do not expose
HasSeed as a public trait. Need to figure out a good workaround...
> ML Pipeline and meta-algs should take random seed param
> -------------------------------------------------------

> Key: SPARK-7653
> URL: https://issues.apache.org/jira/browse/SPARK-7653
> Project: Spark
> Issue Type: Improvement
> Components: ML
> Reporter: Joseph K. Bradley
> Priority: Minor
>
> ML Pipelines and other meta-algorithms should implement HasSeed. If the seed
> is set, then the meta-alg will use that seed to generate new seeds to pass to
> every component PipelineStage.
> This will make it easier for users to have reproducible results for entire
> pipelines (rather than setting the seed for each stage manually).
