[jira] [Created] (SPARK-10195) Spark SQL's internal types should not be exposed via data sources Filter interfaces

Josh Rosen created SPARK-10195:
----------------------------------

             Summary: Spark SQL's internal types should not be exposed via data sources Filter interfaces
                 Key: SPARK-10195
                 URL: https://issues.apache.org/jira/browse/SPARK-10195
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 1.4.1, 1.4.0, 1.5.0
            Reporter: Josh Rosen
            Assignee: Josh Rosen
            Priority: Critical


Spark SQL's data sources API exposes Catalyst's internal types through its Filter interfaces. This is a problem because types like UTF8String are not stable developer APIs and should not be exposed to third-parties.
