Assignee: (was: xiepengjie)
> Drop partition throws exception with 'Failed to delete parent: File does not
> exist' when the partition's parent path does not exists
> ------------------------------------------------------------------------------------------------------------------------------------
>
> Key: HIVE-22040
> URL: https://issues.apache.org/jira/browse/HIVE-22040
> Project: Hive
> Issue Type: Improvement
> Components: Metastore
> Affects Versions: 1.2.1
> Reporter: xiepengjie
> Priority: Major
>
> I create a manage table with multi partition columns, when i try to drop
> partition throws exception with 'Failed to delete parent: File does not
> exist' when the partition's parent path does not exist. The partition's
> metadata in mysql has been deleted, but the exception is still thrown. it
> will failed if using jdbc by java to connec hiveserver2, I think it is very
> unfriendly and we should fix it.
> Example:
> -- First, create manage table with nulti partition columns, and add
> partitions:
> {code:java}
> drop table if exists t1;
> create table t1 (c1 int) partitioned by (year string, month string, day
> string);
> alter table t1 add partition(year='2019', month='07', day='01');{code}
> -- Second, delete the path of partition 'month=07':
>
> {code:java}
> hadoop fs -rm -r
> /user/hadoop/xiepengjietest.db/drop_partition/year=2019/month=07{code}
>
> -- Third, when i try to drop partition, the metastore throws exception with
> 'Failed to delete parent: File does not exist' .
>
> {code:java}
> alter table t1 drop partition partition(year='2019', month='07', day='01');
> {code}
> exception like this:
>
>
> {code:java}
> Error: Error while processing statement: FAILED: Execution Error, return code
> 1 from org.apache.hadoop.hive.ql.exec.DDLTask. Failed to delete parent: File
> does not exist:
> /user/hadoop/xiepengjietest.db/drop_partition/year=2019/month=07
