Are you still seeing this issue?  How are you running the program?
Can you comment out the part of the test where it deletes it tmp dir
and look at the logs after the test?  Should be something like
/tmp/macc-<UUID>/logs.   I am wondering if the zookeeper server is
dying for some reason, there should be a log for the zookeeper server.

Thanks.
