 communicate with HDFS. To achieve good ingest and query performance, sufficient
 network bandwidth must be available between any two machines.
+In addition to needing access to ports associated with HDFS and ZooKeeper, Accumulo will

+use '0' instead of an explicit value, should, in most cases, work around any issues of
+running multiple distinct Accumulo instances (or any other process which tries to use the
+same default ports) on the same hardware.
