Chen Song created SPARK-6899:
--------------------------------
Summary: Type mismatch when user codegen
Key: SPARK-6899
URL: https://issues.apache.org/jira/browse/SPARK-6899
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 1.3.0
Reporter: Chen Song
When I run tests in DataFrameSuite with codegen on, some type mismatched error
occured.
test("average") {
checkAnswer(
decimalData.agg(avg('a)),
Row(new java.math.BigDecimal(2.0)))
}
type mismatch;
found : Int(0)
required: org.apache.spark.sql.types.DecimalType#JvmType
The original problem I think comes from GenerateMutableProjection.
