Subject [jira] [Created] (HIVE-11194) Exchange partition on external tables should fail with error message when target folder already exists
Date Tue, 07 Jul 2015 21:16:05 GMT
Aihua Xu created HIVE-11194:
-------------------------------

             Summary: Exchange partition on external tables should fail with error message
when target folder already exists
                 Key: HIVE-11194
                 URL: https://issues.apache.org/jira/browse/HIVE-11194
             Project: Hive
          Issue Type: Bug
          Components: Hive
    Affects Versions: 2.0.0
            Reporter: Aihua Xu
            Assignee: Aihua Xu


Steps to repro:
{noformat}
Create /data/a1/pkey=1 directory with some data in it.
Create /data/a2/pkey=1 directory with some data in it.

create external table a1 (value string) partitioned by (pkey int) location '/data/a1';
create external table a2 (value string) partitioned by (pkey int) location '/data/a2';
alter table a2 add partition (pkey=1);
alter table a1 exchange partition (pkey=1) with table a2;
select * from a1 should now fail.
{noformat}

pkey=1 is not a partition of a1 but the folder exists. We should give an error message for
that.
