simple cluster setup

[Drew Pierce]

Trying to get a 1.4.2 cluster setup. Are there any simple steps as the 
permutations of woe on EC2 are many, such as the IP addresses (elastic IP's, 
local ip's) to use in masters/slaves, and are the slaves using a single 
zookeeper server or their own on localhost. Are ssh passphraseless keys 
required, and if so, which user? user accumulo's authorized keys? There just 
lacks any detail. The slave nodes report that there is no master server. Thx.
