[jira] [Updated] (HIVE-2242) DDL Semantic Analyzer does not pass partial specification partitions to PreExecute hooks when dropping partitions

["Sohan Jain (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HIVE-2242?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Sohan Jain updated HIVE-2242:
-----------------------------

    Description: 
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"
