Lars George commented on HBASE-8480:
------------------------------------

[~otis] I agree that this is something that needs to be carefully thought 
about. But on the other hand a lot of things have happened since then, HBase 
and HDFS have seen many optimizations that makes this more feasible today. 
Sure, I agree with what [~streamy] commented in the thread, we will see users 
overdo it caused by additional overload of the same single or small cluster 
setup. But that was always the case.

I believe we need to also compete with the smaller, easier to get going with 
NoSQL solutions.

But then we also should have a Bootstrap backed website :)

> 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.
