You would have to have separate conf file for each datanode,
basically you need to have different datanode address
(dfs.datanode.address and related)
and different storage directories dfs.data.dir. Have different
configs and start each datanode instance with different conf
directory containing different conf file

Subject: multiple datanodes on single node cluster
Hi all,
Is it possible to run multiple datanode instances on single node
hadoop
cluster?
How to do that?
thanks,

The minicluster also allows multiple data nodes in the same JVM.
This normally used only for testing. See DataNodeCluster under src/test.
This is probably not what you are looking for but I thought I would
mention it.
