Subject [jira] [Commented] (CURATOR-47) Two leaders in the leader election recipe
Date Mon, 15 Jul 2013 11:30:48 GMT


Germán Blanco commented on CURATOR-47:

Thanks a lot for using some of your time to take a look at this!
The attached patch is on curator 2.0.1 as checked-out using: "git checkout apache-curator-2.0.1"
from the git repository cloned from
The change is on file
The rest of curator libraries were also compiled from that version, but I have tried version
2.1.0 from Maven Central and also came up with the error.
Maybe OS and JDK have something to do with it. I am using Windows 7 and Oracle JDK 1.7.0.
