--------------------------------------------------------
Summary: PCRExprProcFactory.GenericFuncExprProcessor.process()
aggressively removes dynamic partition pruner generated synthetic join
predicates.
Key: HIVE-12666
URL: https://issues.apache.org/jira/browse/HIVE-12666
Project: Hive
Issue Type: Bug
Reporter: Hari Sankar Sivarama Subramaniyan
Assignee: Hari Sankar Sivarama Subramaniyan
Introduced by HIVE-11634. The original idea in HIVE-11634 was to remove the IN
partition conditions from the predicate list since the static dynamic
partitioning would kick in and push these predicates down to metastore.
However, the check is too aggressive and removes events such as below :
{code}
- Select Operator
- expressions: UDFToDouble(UDFToInteger((hr / 2))) (type:
double)
- outputColumnNames: _col0
- Statistics: Num rows: 1 Data size: 7 Basic stats:
COMPLETE Column stats: NONE
- Group By Operator
- keys: _col0 (type: double)
- mode: hash
- outputColumnNames: _col0
- Statistics: Num rows: 1 Data size: 7 Basic stats:
COMPLETE Column stats: NONE
- Dynamic Partitioning Event Operator
- Target Input: srcpart
- Partition key expr: UDFToDouble(hr)
- Statistics: Num rows: 1 Data size: 7 Basic stats:
COMPLETE Column stats: NONE
- Target column: hr
- Target Vertex: Map 1
{code}
