Hi: I am trying to fix (or understand, hence how to fix) this compile error with zookeeper, v3.5.6, and am seeing failures. Specifically, mvn test fails in some very specific tests. I am not sure that it has anything to do directly with centos, per se.

Is there a specific version of java and zookeeper I should be using? Something else I should look at? Thanks, Kannan
