Can we use a replication factor of 3 with only one Data node ? 

Your reply is very much appreciated

Technically, yes. The system will give warnings and you will show a lot of under-replicated blocks but it will continue to function.

It is better to just adjust the replication factor unless this will be an short lived cluster.
