Adam Kramer commented on HIVE-2826:
-----------------------------------

Ugh, sorry. The weird difference in syntax is what made me think this had not been implemented.

> Support for ALTER TABLE x ADD IF NOT EXISTS PARTITION was added in HIVE-1106. The same
semantics should be supported for ALTER VIEW.
> WAS:
> When trying to add a partition, if the partition already exists, we shouldn't necessarily
cause the job to fail...just like we have CREATE TABLE IF NOT EXISTS and DROP TABLE IF EXISTS,
we should have ALTER TABLE foo ADD PARTITION IF NOT EXISTS (ds=whatever).
> Ditto for ALTER VIEW.
