Rakesh R commented on ZOOKEEPER-2139:
-------------------------------------

*Adding one more use case:*

Consider a case where my application needs to talk to multiple ZooKeeper 
clusters whose principals are different. Here the zookeeper client should have 
the intelligence(configuration details) to connect to two different clusters. 

I think, with the proposed solution {{ZooKeeper(String connectString, int 
sessionTimeout, Watcher watcher, Configuration conf)}}, the ZooKeeper client 
can accept the respective configuration through the constructor and instantiate 
it using the passed configuration values.

> Zookeeper client configuration should not be java system property

> I have two ZK client in one JVM, one is secure client and second is normal 
> client (For non secure cluster).
> "zookeeper.sasl.client" system property is "true" by default, because of this 
> my second client connection is failing.
> We should pass all client configurations in client constructor like HDFS 
> client.
> For example :
> {code}
> public ZooKeeper(String connectString, int sessionTimeout, Watcher watcher, 
> Configuration conf) throws IOException
>       {
>               ......
>               ......
>       }
> {code}
