[~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

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
