> {{_checkThresholdConsistency}} incorrectly uses {{getParam}} in attempt to
> access {{threshold}} and {{thresholds}} values. Furthermore it calls it with
> {{Param}} instead of {{str}}:
> {code}
> >>> from pyspark.ml.classification import LogisticRegression
> >>> lr = LogisticRegression(threshold=0.25, thresholds=[0.75, 0.25])
> Traceback (most recent call last):
> ...
> TypeError: getattr(): attribute name must be string
> {code}
> Finally exception message uses {{join}} without converting values to {{str}}.
