Is there a benefit to using hadoop with only one node? I just started learning about Hadoop. From what I understand its primary strength is its ability to distribute a task across many nodes. Is there any benefit to using Hadoop with only a single node, other then the potential of expanding to more nodes in the future? What if you have no plans of ever having more then one node? Or is there an expectation that if you are going to use Hadoop you are also going to be setting up a cluster of many nodes?
If you are testing or building something that will eventually be run on a distributed cluster, yes it make sense. If you're playing around to learn, yes. Otherwise no I don't see much value.
