> Key: SPARK-42292
> URL: https://issues.apache.org/jira/browse/SPARK-42292
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 3.2.1
> Reporter: xuanzhiang
> Priority: Major
>
> I use spark3 to count partition num , like :
> table a is external parquet table, it have 3 partition columns (year ,month,
> day).
> query sql : "select distinct month , day from a where year = '2022' "
> i think spark can find hive metadata and use partition info, but it load all
> "year = '2022'" partition data.
> in spark2.4, it use TableLocalScanExec ,but spark3 use HiveTableRelation and
> scan hive parquet.
