if you have time, maybe take a look at #1612 ? it is about this ticket,
https://issues.apache.org/jira/browse/SPARK-2710 , test suite just added.
it will be a good feature for some use cases, such as we use RDBMS (OLTP)
to store daily incremental data, and full data stored in Hadoop, we want to use
Spark SQL to join or union the tables from these two data source. now we must
hard code case class for each tables came from JDBC...
and i find this one for CSV #1351 , it seems it is a good sample for adding
new SchemaRDD types, need also to add some interface in sql.py and
JavaSQLContext right?
