Alan Gates commented on HIVE-7241:
----------------------------------
The list of locks there just covers the older ZK and memory lock models. The
locks for DbLockMgr are completely different. They are covered briefly in
https://cwiki.apache.org/confluence/display/Hive/Hive+Transactions#HiveTransactions-LockManager
but not listed individually, so there's no need to add this change in the
documentation.

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