[jira] [Updated] (SPARK-2342) Evaluation helper's output type
doesn't conform to input type
[ https://issues.apache.org/jira/browse/SPARK-2342?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Yijie Shen updated SPARK-2342:
------------------------------
Description:
In sql/catalyst/org/apache/spark/sql/catalyst/expressions.scala
{code}protected final def n2 ( i: Row, e1: Expression, e2: Expression, f: ((Numeric[Any], Any, Any) => Any)): Any {code}
is intended to do computations for Numeric add/Minus/Multipy.
Just as the comment suggest : {quote}Those expressions are supposed to be in the same data type, and also the return type.{quote}
But in code, function f was casted to function signature:
{code}(Numeric[n.JvmType], n.JvmType, n.JvmType) => Int{code}
I thought it as a typo and the correct should be:
{code}(Numeric[n.JvmType], n.JvmType, n.JvmType) => n.JvmType{code}
was:
