Reynold Xin updated SPARK-13139:
--------------------------------
    Description: 
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.

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.
