> User should able to overwrite partition for a specific partition. Like
> {code}
> INSERT OVERWRITE TABLE partitioned_user
>       PARTITION (country = 'US')
>       SELECT * FROM another_user au 
>       WHERE au.country = 'US';
> {code}
> In the above example, the user can overwrite only the partition(country = 'US') data.
So remaining partitions data would be intact.  
> While overwriting a specific partition carbon should first load data to the new segment
and drop that partition from all remaining segments using partition.map file.
