> 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.
