The reason for that was to return a Pair and not have to add on an
implementation for a Pair, or to have a custom Object definition for that - do
you have a preference in how else to do that?

bq. Testing
bq. -------
bq.
bq. Modified TestHiveMetaStore.partitionTester() to add tests for the
following scenarios:
bq.
bq. + add_partition(empty list) : no exceptions thrown : works
bq. + add_partitions(list containing 3 partitions) : works, verified that
partitions exist
bq. + 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.
bq. + add_partitions(list with a single partition) : works, does not fault on
duplicate as a result of a partial publish above.
bq. + verified that all above created partitions exist : works
bq.
bq. All of the above is called from both TestEmbeddedHiveMetaStore and
TestRemoteHiveMetaStore
bq.
