Yijie Shen created SPARK-2342: --------------------------------- Summary: Evaluation helper's output type doesn't conform to input type Key: SPARK-2342 URL: https://issues.apache.org/jira/browse/SPARK-2342 Project: Spark Issue Type: Bug Components: SQL Affects Versions: 1.0.0 Reporter: Yijie Shen Priority: Minor
In sql/catalyst/org/apache/spark/sql/catalyst/expressions.scala protected final def n2 ( i: Row, e1: Expression, e2: Expression, f: ((Numeric[Any], Any, Any) => Any)): Any is intended to do computations for Numeric add/Minus/Multipy. Just as the comment suggest : "Those expressions are supposed to be in the same data type, and also the return type." But in code, function f was casted to function signature: (Numeric[n.JvmType], n.JvmType, n.JvmType) => Int I thought it as a typo and the correct should be: (Numeric[n.JvmType], n.JvmType, n.JvmType) => n.JvmType -- This message was sent by Atlassian JIRA (v6.2#6252)
