Ryu Kobayashi created HIVE-27939:
------------------------------------
Summary: Many UNION ALL throws SemanticException when trying to
remove partition predicates: fail to find child from parent
Key: HIVE-27939
URL: https://issues.apache.org/jira/browse/HIVE-27939
Project: Hive
Issue Type: Bug
Components: Query Processor
Affects Versions: 4.0.0-beta-1
Reporter: Ryu Kobayashi
Attachments: ddl.sql, query.sql
I found that the ticket for HIVE-26779 alone does not resolve when using many
UNION ALL. When we create a DDL with ddl.sql and execute a query with
query.sql, we get a SemanticException similar to HIVE-26779.
