Thanks for the comments.  Yes, I changed the code at DataSourceStrategy, but 
the change is independent to the Cast in 9182.

[~huaxing] Maybe we should do this one first 
https://issues.apache.org/jira/browse/SPARK-9182.

I guess you might be thinking of the change of some codes at 
{{DataSourceStrategy}} or making this with {{CatalystScan}}, right?

In case of {{CatalystScan}}, I opened the issue here already, 
https://issues.apache.org/jira/browse/SPARK-12126.

In case of {{DataSourceStrategy}}, We might need to deal with {{Cast}} first.
