Sean R. Owen resolved SPARK-28853.
----------------------------------
Resolution: Won't Fix
> Support conf to organize filePartitions by file path
> -----------------------------------------------------
>
> Key: SPARK-28853
> URL: https://issues.apache.org/jira/browse/SPARK-28853
> Project: Spark
> Issue Type: New Feature
> Components: SQL
> Affects Versions: 3.0.0
> Reporter: ZhangYao
> Priority: Major
>
> When dynamicly writing data to hdfs it may generates a lot of small files, so
> sometimes we need to merge those files. When reading this files and writing
> again, it will be helpful if the read file RDD partitions is formed by
> partitions on hdfs.
> Currently in FileSourceScanExec.createNonBucketedReadRDD after spliting
> files, spark will sort files with file size so it may scatter the partition
> distribution of the data files. It is a great help to support sort by file
> path here :)
