> This issue introduces the ability for the HMaster to make use of ZooKeeper's 
> multi-update functionality.  This allows certain ZooKeeper operations to 
> complete more quickly and prevents some issues with rare ZooKeeper failure 
> scenarios (see the release note of HBASE-6710 for an example).  This feature 
> is off by default; to enable set "hbase.zookeeper.useMulti" to true in the 
> configuration of the HMaster.
> IMPORTANT: "hbase.zookeeper.useMulti" should only be set to true if all 
> ZooKeeper servers in the cluster are on version 3.4+ and will not be 
> downgraded.  ZooKeeper versions before 3.4 do not support multi-update and 
> will not fail gracefully if multi-update is invoked (see ZOOKEEPER-1495).
