 All Accumulo processes running on a cluster are locatable via zookeeper.  Therefore using
well known ports is not really required.  [ACCUMULO-1664][ACCUMULO-1664] makes it possible
to for all Accumulo processes to use random ports.  This makes it easier to run multiple Accumulo
instances on a single node.

not have IPv6 completely disabled can cause strange failures. [ACCUMULO-2262][ACCUMULO-2262]
invokes the JVM-provided configuration parameter at process startup to prefer IPv4 over IPv6.
