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.
+While Hadoop [does not support IPv6 networks][3], attempting to run on a system that does 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.
