Lefty Leverenz commented on HIVE-7241:
--------------------------------------
The wiki's Locking doc doesn't include "alter table T1 partition P1 rename to
partition P2" so it ought to be added to the table of Hive commands and locks
acquired in the Use Cases section:
* [Hive Concurrency Model -- Use Cases |
https://cwiki.apache.org/confluence/display/Hive/Locking?from=_YKhAQ#Locking-UseCases]
> Wrong lock acquired for alter table rename partition

> acquires a read lock on table foo. It should instead acquire an exclusive
> lock on partition bar=x.
