             Summary: rename some APIs and classes to make their meaning clearer
                 Key: SPARK-22400
                 URL: https://issues.apache.org/jira/browse/SPARK-22400
             Project: Spark
          Issue Type: Sub-task
          Components: SQL
    Affects Versions: 2.3.0
            Reporter: Zhenhua Wang


Both `ReadSupport` and `ReadTask` have a method called `createReader`, but they create different things. This could cause some confusion for data source developers. The same problem exists between `WriteSupport` and `DataWriterFactory`, both of which have a method called `createWriter`.

Besides, the name of `RowToInternalRowDataWriterFactory` is not correct, because it actually converts `InternalRow`s to `Row`s.
