>    Affects Versions: 0.13.0, 0.14.0, 0.13.1

> ZooKeeperHiveLockManager does not use zookeeper in the proper way. 
> Currently a new zookeeper client instance is created for each 
> getlock/releaselock query which sometimes causes the number of open 
> connections between
> HiveServer2 and ZooKeeper exceed the max connection number that zookeeper 
> server allows. 
> To use zookeeper as a distributed lock, there is no need to create a new 
> zookeeper instance for every getlock try. A single zookeeper instance could 
> be reused and shared by ZooKeeperHiveLockManagers.
