Subject [jira] [Commented] (HIVE-14988) Support INSERT OVERWRITE into a partition on transactional tables
Date Tue, 18 Jul 2017 04:53:00 GMT


Wei Zheng commented on HIVE-14988:

[~leftylev] Thanks for catching that. INSERT OVERWRITE is not a new feature, so I don't think
we need to highlight this. But we do need to remove one bullet item under here:
"As of Hive 0.14, if a table has an OutputFormat that implements AcidOutputFormat and the
system is configured to use a transaction manager that implements ACID, then INSERT OVERWRITE
will be disabled for that table.  This is to avoid users unintentionally overwriting transaction
history.  The same functionality can be achieved by using TRUNCATE TABLE (for non-partitioned
tables) or DROP PARTITION followed by INSERT INTO."
