> HiveServer2 could use Zookeeper to store token that indicate that particular 
> tables are locked with the creation of persistent Zookeeper objects. 
> A problem can occur when a HiveServer2 instance creates a lock on a table and 
> the HiveServer2 instances crashes ("Out of Memory" for example) and the locks 
> are not released in Zookeeper. This lock will then remain until it is 
> manually cleared by an admin.
> There should be a way to remove stale locks at HiveServer2 initialization, 
> helping the admins life.
