-----------------------------------
Hi [~mengxr], I created a pull request to change regex to parseInt and
parseDouble:
https://github.com/apache/spark/pull/12360
Please let me know if there are any issues.
> RandomForest should use parseInt and parseDouble for feature subset size
> instead of regexes
