Aihua Xu commented on HIVE-11130:
---------------------------------
[~alangates] Yes. supportsExplicitLock() is being checked in DDLTask.java for
unlock/lock database/table before doing the real work.
> Refactoring the code so that HiveTxnManager interface will support
> lock/unlock table/database object

> This is just a refactoring step which keeps the current logic, but it exposes
> the explicit lock/unlock table and database in HiveTxnManager which should
> be implemented differently by the subclasses ( currently it's not. e.g., for
> ZooKeeper implementation, we should lock table and database when we try to
> lock the table).
