------------------------------------
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.
