Benjamin Reed commented on ZOOKEEPER-78:
----------------------------------------

Can we focus on the issue at hand? This patch is almost done there is no reason 
for the meta physical discussions or even an external SVN. It's simple enough. 
The only thing that must be done is to remove the use of the ZooKeeperFacade 
and use the ZooKeeper object correctly. If you want to discuss why 
ZooKeeperFacade is a bad idea, lets open an issue to discuss there.

I really like the idea of using the Lock interface, but changing aquire to 
lock() should be good enough.

Lets get this thing committed so that we can move on.

> added a high level protocol/feature - for easy Leader Election or exclusive 
> Write Lock creation

> Here's a patch which adds a little WriteLock helper class for performing 
> leader elections or creating exclusive locks in some directory znode. Note 
> its an early cut; am sure we can improve it over time. The aim is to avoid 
> folks having to use the low level ZK stuff but provide a simpler high level 
> abstraction.
