[jira] [Created] (SPARK-4842) Use WeakTypeTags in ScalaReflection

Michael Armbrust created SPARK-4842:
---------------------------------------

             Summary: Use WeakTypeTags in ScalaReflection
                 Key: SPARK-4842
                 URL: https://issues.apache.org/jira/browse/SPARK-4842
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 1.2.0
            Reporter: Michael Armbrust
            Priority: Critical


Right now we can't create SchemaRDDs from RDDs of case classes that are defined inside of functions.  This is because only WeakTypeTags are available in this scope.  This is pretty confusing to users:
