Zookeeper 3.5.1
(https://github.com/apache/zookeeper/releases/tag/release-3.5.1) dynamic
configuration fails with two servers that are started one after the other
throwing an EOFException. This is the same, if server 2 is configured as
observer or participant. Is the usage wrong? Is this a known bug?
