--------------------------------------
(cc [~cloud_fan], I don't mind reopening this and resolving it separately.)
> Empty files should be skipped while write to file

> Key: SPARK-21435
> URL: https://issues.apache.org/jira/browse/SPARK-21435
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 2.2.0
> Reporter: Li Yuanjian
> Priority: Minor
>
> Consider of this scenario, source table has many partitions and data files,
> after the query filter, only a few data write to the destination dir.
> In this case the destination dir or table will have many empty files or files
> only have schema meta(parquet format), I know we can use coalesce but skip
> the empty file may be more better in this case.
