> I'd like to see an atomic version of the add_partitions() call.
> Whether this is to be done by config to affect add_partitions() behaviour
> (not my preference) or just changing add_partitions() default behaviour (my
> preference, but likely to affect current behaviour, so will need others'
> input) or by making a new add_partitions_atomic() call depends on discussion.
> This looks relatively doable to implement (will need a dependent
> add_partition_core to not do a ms.commit_partition() early, and to cache list
> of directories created to remove on rollback, and a list of AddPartitionEvent
> to trigger in one shot later)
> Thoughts? This also seems like something to implement for allowing HIVE-1805.
