---------------------------------

             Summary: DataSourceV2 should support named tables in 
DataFrameReader, DataFrameWriter
                 Key: SPARK-23204
                 URL: https://issues.apache.org/jira/browse/SPARK-23204
             Project: Spark
          Issue Type: Sub-task
          Components: SQL
    Affects Versions: 2.3.0
            Reporter: Ryan Blue


DataSourceV2 is currently only configured with a path, passed in options as 
`path`. For many data sources, like JDBC, a table name is more appropriate. I 
propose testing the "location" passed to load(String) and save(String) to see 
if it is a path and if not, parsing it as a table name and passing "database" 
and "table" options to readers and writers.
