Description

HBase is often a bit more involved to get going. We already have the option to host ZooKeeper for very small clusters. We should have the same for HDFS. The idea is that it adjusts replication based on the number of nodes, i.e. from 1 to 3 (the default), so that you could start with a single node and grow the cluster from there. Once the cluster reaches a certain size, and the admin decides to split the components, we should have a why to export the proper configs/settings so that you can easily start up an external HDFS and/or ZooKeeper, while updating the HBase config as well to point to the new "locations".

The goal is to start a fully operational HBase that can grow from single machine to multi machine clusters with just a single daemon on each machine.
