> Support recursiveFileLookup for partitioned datasource
> ------------------------------------------------------
>
> Key: SPARK-40600
> URL: https://issues.apache.org/jira/browse/SPARK-40600
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.1.1
> Environment: Spark: 3.1.1
> Hive: 3.1.2
> Reporter: Zhen Wang
> Priority: Major
>
> I use hive tez engine to execute union statement and insert into partitioned
> table may generate HIVE_UNION_SUBDIR subdirectory, and when I use spark sql
> to read this partitioned table, the data below HIVE_UNION_SUBDIR is not read.
> For non-partitioned table, I can read the subdirectories of the table when
> setting recursiveFileLookup to true, but for partitioned table, it seems
> impossible to set recursiveFileLookup to true.
> So I want to support recursiveFileLookup for partitioned table.
