Shuo Xiang 775e6f9909 [SPARK-7694] [MLLIB] Use getOrElse for getting the threshold of LR model ... The `toString` method of `LogisticRegressionModel` calls `get` method on an Option (threshold) without a safeguard. In spark-shell, the following code `val model = algorithm.run(data).clearThreshold()` in lbfgs code will fail as `toString `method will be called right after `clearThreshold()` to show the results in the REPL.
