> Create native DDL commands
> --------------------------
>
> Key: SPARK-13139
> URL: https://issues.apache.org/jira/browse/SPARK-13139
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Reporter: Reynold Xin
>
> We currently delegate most DDLs directly to Hive, through NativePlaceholder
> in HiveQl.scala. In Spark 2.0, we want to provide native implementations for
> DDLs for both SQLContext and HiveContext.
> The first step is to properly parse these DDLs, and then create logical
> commands that encapsulate them. The actual implementation can still delegate
> to HiveNativeCommand. As an example, we should define a command for
> RenameTable with the proper fields, and just delegate the implementation to
> HiveNativeCommand (we might need to track the original sql query in order to
> run HiveNativeCommand, but we can remove the sql query in the future once we
> do the next step).
> Once we flush out the internal persistent catalog API, we can then switch the
> implementation of these newly added commands to use the catalog API.
