Issue Type: Sub-task (was: Bug)
Parent: SPARK-27589
> File source V2: Ignore empty files in load
> ------------------------------------------
>
> Key: SPARK-27291
> URL: https://issues.apache.org/jira/browse/SPARK-27291
> Project: Spark
> Issue Type: Sub-task
> Components: SQL
> Affects Versions: 3.0.0
> Reporter: Gengliang Wang
> Assignee: Gengliang Wang
> Priority: Major
> Fix For: 3.0.0
>
>
> In https://github.com/apache/spark/pull/23130, all empty files are excluded from target file splits in `FileSourceScanExec`.
> In File source V2, we should keep the same behavior.
> This PR suggests to filter out empty files on listing files in `PartitioningAwareFileIndex` so that the upper level doesn't need to handle them.
