> Project: Hive
> Issue Type: Improvement

>
> Currently add_partitions() api sends all the partitions (new partitions and
> existing partitions) that need to be added for authorization, instead, we can
> optimize this by sending only the new partitions for authorization.
> Impact: Alter table recover partitions collects all the available partitions
> and sends it to Metastore to check if any new partitions can be added. If all
> the partitions are sent for authorization irrespective of whether it exists
> or not, the Authorization service will unnecessarily spend time on
> authorizing already existing partitions. This can be avoided by only
> authorizing new partitions.
