[jira] [Created] (SPARK-27132) Improve file source V2 framework

Gengliang Wang created SPARK-27132:
--------------------------------------

             Summary: Improve file source V2 framework
                 Key: SPARK-27132
                 URL: https://issues.apache.org/jira/browse/SPARK-27132
             Project: Spark
          Issue Type: Task
          Components: SQL
    Affects Versions: 3.0.0
            Reporter: Gengliang Wang


During the migration of CSV V2, I find that we can improve the file source v2 framework by:
1. check duplicated column names in both read and write
2. Not all the file sources support filter push down. So remove `SupportsPushDownFilters` from FileScanBuilder
3. The method `isSplitable` might require data source options. Add a new member `options` to FileScan.
