Peter Vary commented on HIVE-14979:

Flaky tests:
* HIVE-14977 org.apache.hadoop.hive.cli.TestCliDriver.testCliDriver[order_null]
* HIVE-14976 
* HIVE-14937 
The other failures are not even flaky (50+ failed runs)
So test failures are not related

The questions above are still valid.

> 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.
