according this discussion similar problem solved re-ordering dependencies. suggest move zookeeper dependency element upper in dependency list.

edit:

i suspect problem comes classpath order issue. i.e. same class present in multiple artifacts , version of offending class loaded the wrong one.

to workaround problem need re-order classpath (you know when same class present multiple time in classpath: first 1 win). reorder classpath need change order of declarations in pom.xml (at least since maven 2.0.9)

quote maven site :

since maven 2.0.9 it's order in declaration counts: first declaration wins.
