Harsh J commented on HIVE-3576:
-------------------------------
Sorry, let me explain with an example:
On 0.7.1:
{code}
hive> create table test(a string) partitioned by (dt string);
OK
Time taken: 21.049 seconds
hive> alter table test drop if exists partition(dt=2007);
OK
Time taken: 1.297 seconds
{code}
On 0.9.0:
{code}
hive> create table test(a string) partitioned by (dt string);
OK
Time taken: 2.133 seconds
hive> alter table test drop if exists partition(dt=2007);
FAILED: SemanticException [Error 10006]: Partition not found dt = 2007
{code}
Again, if we make sure to use 'strings', on 0.9.0, it works:
{code}
hive> alter table test drop if exists partition(dt='2007');
OK
Time taken: 0.684 seconds
{code}
> Regression: ALTER TABLE DROP IF EXISTS PARTITION throws a SemanticException
> if Partition is not found

> Key: HIVE-3576
> URL: https://issues.apache.org/jira/browse/HIVE-3576
> Project: Hive
> Issue Type: Bug
> Components: Query Processor
> Affects Versions: 0.9.0
> Reporter: Harsh J
>
> Doing a simple "{{ALTER TABLE testtable DROP IF EXISTS
> PARTITION(dt=NONEXISTENTPARTITION)}}" fails with a SemanticException of the
> 10006 kind (INVALID_PARTITION).
> This does not respect the {{hive.exec.drop.ignorenonexistent}} condition
> either, since there are no if-check-wraps around this area, when fetching
> partitions from the store.
