@mpjlu This is the behavior I get:
````scala
scala> import org.apache.spark.ml.classification.LogisticRegression
import org.apache.spark.ml.classification.LogisticRegression
scala> val lr = new LogisticRegression()
lr: org.apache.spark.ml.classification.LogisticRegression =
logreg_2465e281c48e
scala> lr.getThresholds
java.util.NoSuchElementException: Failed to find a default value for
thresholds
...
````
So, it throws an exception when nothing is set, as intended it seems.
