Adam Kramer commented on HIVE-2826:
-----------------------------------
Also, it is implemented for views, too.
> ALTER VIEW ADD PARTITION needs IF NOT EXISTS.

> Key: HIVE-2826
> URL: https://issues.apache.org/jira/browse/HIVE-2826
> Project: Hive
> Issue Type: Improvement
> Reporter: Adam Kramer
>
> 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.
