Ability to add_partitions atomically
------------------------------------
Key: HIVE-2224
URL: https://issues.apache.org/jira/browse/HIVE-2224
Project: Hive
Issue Type: Improvement
Components: Metastore
Reporter: Sushanth Sowmyan
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.
