Re: ClassCastException when use spark1.5.1

I'm not sure why this would have have changed from 1.4.1 to 1.5.1, but I have
seen similar exceptions in my code. It seems to me that values with SQL type
"ArrayType" are stored internally as an instance of the Scala "WrappedArray"
class (regardless if is was originally an instance of Scala "List"). To deal
with this, I would just change List to Seq when calling "getAs".

TLDR:
val risk_items = r.getAs[Seq[Map[String, String]]]("risk_items")
