Benjamin Reed commented on ZOOKEEPER-78:
----------------------------------------
I've documented on the wiki at
http://wiki.apache.org/hadoop/ZooKeeper/ErrorHandling why ZooKeeperFacade needs
to be removed. Just use the ZooKeeper object. For this patch in particular it
is very important not to use a facade.
> 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.
