------------------------------
Summary: 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
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
