Zhenhua Wang updated SPARK-22400:
---------------------------------
Description:
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 issue 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.
