Takeshi Yamamuro commented on SPARK-14525:
------------------------------------------
Yeah, +1. I'm not sure we have a special handling for the `jdbc` source. I
think it would be better to move all the jdbc functionality of
`DataFrameWriter` into `jdbc.DefaultSource`, then duplicate
`read.format("jdbc").
> DataFrameWriter's save method should delegate to jdbc for jdbc datasource

> Key: SPARK-14525
> URL: https://issues.apache.org/jira/browse/SPARK-14525
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 1.6.1
> Reporter: Justin Pihony
> Priority: Minor
>
> If you call {code}df.write.format("jdbc")...save(){code} then you get an
> error
> bq. org.apache.spark.sql.execution.datasources.jdbc.DefaultSource does not
> allow create table as select
> save is a more intuitive guess on the appropriate method to call, so the user
> should not be punished for not knowing about the jdbc method.
> Obviously, this will require the caller to have set up the correct parameters
> for jdbc to work :)
