[jira] [Resolved] (CURATOR-53) PersistentEphemeralNode does not work when ZK server are not available when the node is started

["Jordan Zimmerman (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/CURATOR-53?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jordan Zimmerman resolved CURATOR-53.
-------------------------------------

    Resolution: Fixed

ensurePath might throw an exception if connection couldn't succeed. The exception was being swallowed by createNode causing the recipe to fail if there wasn't a good connection when the object was started. Switched to use creatingParentsIfNeeded. It's more efficient anyway. Also, fixed swallowed exceptions.
   
TODO - check other recipes' uses of ensurePath for similar problem.

> This sequence is not working:
> // ZK servers are not started here
> ExponentialBackoffRetry retryPolicy = new ExponentialBackoffRetry(1000, 1, 2000);
> CuratorFramework zkClient = CuratorFrameworkFactory.newClient("127.0.0.1:30101", 
> 4500,
> 4500,
> retryPolicy);
> zkClient.start();
> Thread.sleep(2000);
> PersistentEphemeralNode pen = new PersistentEphemeralNode(zkClient, Mode.EPHEMERAL, "/abc/pen", "hello".getBytes());
> Thread.sleep(2000);
> // Start ZK servers here
> Thread.sleep(2000);
> // "/abc/pen" ephemeral node is not created
> It is expected that once the CuratorFrameowrk is connected the ephemeral node is created
> I attach a program that shows the failure
