-----------------------------------------------

@Ted
Thanks for adding the change ZKUtil.java also.  What could be the reason for 
the node not to exist and why was a new connection established?
These 2 we may have to figure out exactly.

> If zookeeper.znode.parent is not specifed explicitly in Client code then 
> HTable object loops continuously waiting for the root region by using /hbase 
> as the base node.

> Change the zookeeper.znode.parent property (default is /hbase).
> Now do not specify this change in the client code.
> Use the HTable Object.
> The HTable is not able to find the root region and keeps continuously looping.
> Find the stack trace:
