-----------------------------------------
Summary: 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
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}}.
