HIVE-3531 [jira] Simple lock manager for dedicated hive server
(Navis Ryu via Carl Steinbach)
Summary:
DPAL-1906 Implement simple lock manager for hive server
In many cases, we uses hive server as a sole proxy for executing all the
queries. For that, current default lock manager based on zookeeper seemed a
little heavy. Simple in-memory lock manager could be enough.
Test Plan: TestDedicatedLockManager
