I've been setting up a MapR cluster.  I've enabled the ports listed here:

 * http://www.mapr.com/doc/display/MapR/Ports+Used+by+MapR

But the Zookeeper instances failed to find each other, logs indicated they are using 2888:3888 as well as 5181.  Adding access rules for 2888 and 3888 corrected the problem.  (I think we may require only 3888 but haven't tested that.)

* Should 3888 be listed for ZK at the site above?
