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.
