>
> 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"
