Description

I tried to see if one could build Hadoop 0.23.0 against ZooKeeper 3.4.0, rather than 3.3.1 (3.3.3 does work, fwiw) and hit compilation errors:

[INFO] ------------------------------------------------------------------------

Presumably, Yarn needs to build against newer ZK releases eventually, hence this bug. =)
