> Exchange Partition with a table that already contains it

>                 Key: HIVE-14763
>                 URL: https://issues.apache.org/jira/browse/HIVE-14763
>             Project: Hive
>          Issue Type: Improvement
>          Components: Metastore
>            Reporter: Konstantinos Kallas
>            Assignee: Konstantinos Kallas
>            Priority: Minor
>              Labels: atomic, partition
> The EXCHANGE PARTITION command fails to execute if the partition already 
> exists in the target table. However this is not the expected result from a 
> command named *EXCHANGE* partition. 
> +Proposed Improvement+
> Change the command to really exchange the partition between the target and 
> the source table, meaning that after it the source table should have the 
> destination table partition and vice versa.
