Documentation for Lock recipe has major flaw
--------------------------------------------
Key: ZOOKEEPER-1262
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1262
Project: ZooKeeper
Issue Type: Bug
Components: documentation
Affects Versions: 3.3.3
Reporter: Jordan Zimmerman
The recipe for Locks documented here:
http://zookeeper.apache.org/doc/trunk/recipes.html#sc_recipes_Locks doesn't
deal with the problem of create() succeeding but the server crashing before the
result is returned. As written, if the server crashes before the result is
returned the client can never know what sequential node was created for it. The
way to deal with this is to embed the session ID in the node name. The Lock
implementation in the ZK distro does this. But, the documentation will lead
implementors to write bad code.
