Wei Zheng commented on HIVE-14988:
----------------------------------
patch 03 is following the "new base" approach proposed by Eugene.
For example, we have such directory layout:
{code}
delta_1_1
delta_2_2
base_2
delta_3
{code}
After an Insert Overwrite, it should become like this:
{code}
delta_1_1
delta_2_2
base_2
delta_3
base_4 <= new base. All other dirs become obsolete.
{code}
> Support INSERT OVERWRITE into a partition on transactional tables
