Denys Kuzmenko updated HIVE-26076:
----------------------------------
Description: Originally X (EXCLUSIVE) lock was used to prevent races
between concurrent add partition calls with IF NOT EXISTS, however, the same
behavior could be achieved with a less restrictive X-write (EXCL_WRITE) lock.
> Non blocking ADD PARTITION if not exists
