------------------------------------
Summary: Cast from BooleanType to NumericType should use exact
type value.
Key: SPARK-1610
URL: https://issues.apache.org/jira/browse/SPARK-1610
Project: Spark
Issue Type: Bug
Components: SQL
Reporter: Takuya Ueshin
Cast from BooleanType to NumericType are all using Int value.
But it causes ClassCastException when the casted value is used by the following
evaluation like the code below:

scala> Add(Cast(Literal(true), ShortType), Literal(1.toShort)).eval()
java.lang.ClassCastException: java.lang.Integer cannot be cast to
java.lang.Short
