This backports [https://github.com//pull/10161] to Spark 1.5, with the difference that ChiSqSelector does not require modification.
Switched from using SQLContext constructor to using getOrCreate, mainly in model save/load methods.
This covers all instances in spark.mllib. There were no uses of the constructor in spark.ml.
