navis requested code review of "HIVE-3531 [jira] Simple lock manager for
dedicated hive server".
Reviewers: JIRA
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.
