[jira] [Updated] (SPARK-7694) Use getOrElse for getting the
threshold of LR model
[ https://issues.apache.org/jira/browse/SPARK-7694?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Shuo Xiang updated SPARK-7694:
------------------------------
Description:
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 toStringmethod will be called right after clearThreshold() to show the results in the REPL.
