Hyukjin Kwon resolved SPARK-11543.
----------------------------------
Resolution: Incomplete
> spark.ml LogisticRegressionModel should prefer thresholds over threshold
> ------------------------------------------------------------------------
>
> Key: SPARK-11543
> URL: https://issues.apache.org/jira/browse/SPARK-11543
> Project: Spark
> Issue Type: Improvement
> Components: ML
> Reporter: Joseph K. Bradley
> Assignee: Xiangrui Meng
> Priority: Major
> Labels: bulk-closed
>
> The current behavior was defined in [SPARK-9847], where the two Params must
> match if both are set. This causes problems for model persistence, for which
> it is easier (for backwards compatibility) to save a single ParamMap instead
> of 2 (user-set + default). This can be fixed by changing LogisticRegression
> to use {{thresholds}} if set (ignoring {{threshold}}), and to otherwise use
> {{threshold}}.
