> If there are multiple threads opening connections to the same Phoenix (HBase)
> instance concurrently, the same ConnectionQueryServicesImpl instance can be
> initialized multiple times. This can eventually cause some resources to leak,
> such as ZK connections.
> There is a synchronized block to prevent this, but PHOENIX-966 inadvertently
> disabled the function of the synchronized block.
