[jira] [Commented] (HIVE-14988) Support INSERT OVERWRITE into a partition on transactional tables

["Wei Zheng (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-14988?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16056621#comment-16056621 ] 

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}
