Apache Spark reassigned SPARK-29786:
------------------------------------
Assignee: (was: Apache Spark)
> Fix MetaException when dropping a partition not exists on HDFS.
> ---------------------------------------------------------------
>
> Key: SPARK-29786
> URL: https://issues.apache.org/jira/browse/SPARK-29786
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 3.0.0
> Reporter: Deegue
> Priority: Major
>
> When we drop a partition which doesn't exist on HDFS, we will receive
> `MetaException`.
> But actually the partition has been dropped.
> In Hive, no exception will thrown in this case.
> For example:
> If we execute alter table test.tmp drop partition(stat_day=20190516);
> (the partition stat_day=20190516 exists on Hive meta, but doesn't exist on
> HDFS)
> We will get :
> {code:java}
> Error: Error running query: MetaException(message:File does not exist:
> /user/hive/warehouse/test.db/tmp/stat_day=20190516
