Re: Odp: Re: hive 4.0.0-alpha2 external table locks

[Denys Kuzmenko]

DbTxnManager doesn't have support for explicit locking. 
You could use HMSClient to issue an explicit lock request or create a lock 
record manually in the backend DB `HIVE_LOCKS` table.
Maybe you could temporarily restrict access to those tables via Ranger or drop 
them from the HMS while performing maintenance?
