-----------------------------------
Summary: Can not pruning hive partitions by Or predicate
Key: SPARK-28983
URL: https://issues.apache.org/jira/browse/SPARK-28983
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 2.4.4
Reporter: huajian lan
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 the object HiveTableScans#apply(plan: LogicalPlan), when the
predicate has any child that contains non-partition column, it will make a
outer FilterExec.
