DDL Semantic Analyzer does not pass partial specification partitions to
PreExecute hooks when dropping partitions
-----------------------------------------------------------------------------------------------------------------
Key: HIVE-2242
URL: https://issues.apache.org/jira/browse/HIVE-2242
Project: Hive
Issue Type: Bug
Components: Query Processor
Reporter: Sohan Jain
Assignee: Sohan Jain
Currently, when dropping partitions, the DDL Semantic Analyzer only passes
partitions that have a full specification to Pre Execution hooks. It should
also include all matches from partial specifications.
E.g., suppose you have a table
{{create table test_table (a string) partitioned by (p1 string, p2 string);
alter table test_table add partition (p1=1, p2=1);
alter table test_table add partition (p1=1, p2=2);
alter table test_table add partition (p1=2, p2=2);
}}
and you run
{{alter table test_table drop partition(p1=1);}}
Pre-execution hooks will not be passed any of the partitions. The expected
behavior is for pre-execution hooks to get the WriteEntity's with the
partitions "p1=1/p2=1" and "p1=1/p2=2"
