Testing
-------
Modified TestHiveMetaStore.partitionTester() to add tests for the following
scenarios:
+ add_partition(empty list) : no exceptions thrown : works
+ add_partitions(list containing 3 partitions) : works, verified that
partitions exist
+ add_partitions(list containing 2 partitions, where one of them has keyvalues
identical to original partition, and another partition has a directory already
created, verified that the call causes an exception, and directories are
unchanged(the one with the dir pre-existing continues to exist), and no
additional partition was published.
+ add_partitions(list with a single partition) : works, does not fault on
duplicate as a result of a partial publish above.
+ verified that all above created partitions exist : works
All of the above is called from both TestEmbeddedHiveMetaStore and
TestRemoteHiveMetaStore

> Ability to add_partitions, and atomically
> -----------------------------------------

> Key: HIVE-2224
> URL: https://issues.apache.org/jira/browse/HIVE-2224

> 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.
