-----------------------------------------
Hmm... cannot the nodes be made ephemeral in ZK, if we indeed want to release
them when we crash?
> Removing stale Zookeeper locks at HiveServer2 initialization

> 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.
