huajian lan updated SPARK-28983:
--------------------------------
Description:
Assume the hive partition table has p1/p2 partition column and c1 non-partition
column,
the below where clause can not prunning partitions in sparksql, but we can
prunning by "p1 = 'a' or p2 = 'b'" in principal.
{code:java}
where
(p1 = 'a' and c1 = 1)
or
(p2 = 'b' and c1 = 2){code}
The problem is in HiveTableScans#apply(plan: LogicalPlan), when the predicate
has any child that contains non-partition column, it will make a outer
FilterExec and empty predicate in HiveTableScanExec.
