             Summary: Allow customizable column name in ScalaReflection.schemaFor
                 Key: SPARK-19322
                 URL: https://issues.apache.org/jira/browse/SPARK-19322
             Project: Spark
          Issue Type: Improvement
          Components: Spark Core
    Affects Versions: 2.1.0
            Reporter: Wei Liu
            Priority: Minor


When creating StructType using Scalarelfection.schemaFor, the column names are defined by scala case class parameter names. This causes minor inconvenience when reading/writing data between Python and Scala. Ideally, we should allow customize column names using Scala annotations in a similar fashion to Jackson serialization libraries.
