He Yongqiang commented on HIVE-1707:
------------------------------------
Yes. We should delete the old data. Even today, if two tables/partitions share
the same location, one delete will delete the data.
Will upload a patch soon. The main problem here is to add testcases. (I can do
tests on internal clusters.)
> bug when different partitions are present in different dfs

> Key: HIVE-1707
> URL: https://issues.apache.org/jira/browse/HIVE-1707
> Project: Hadoop Hive
> Issue Type: Bug
> Components: Query Processor
> Reporter: Namit Jain
> Assignee: He Yongqiang
> Fix For: 0.7.0
>
>
> The following does not work:
> create table T -> default location dfs1
> insert overwrite T partition (ds='1') select * from src;
> alter table T location 'dfs2';
> insert overwrite T partition (ds='1') select * from src;
> It tries to insert back in dfs1 - due to which the move task fails.
> It would be cleaner to keep the same semantics as fileformat - whenever a
> partition is being inserted into, it
> inherits the properties from the table. So, after the insert, the partition
> should belong to dfs1.
> It does not matter whether the partition exists before or not,.
