Re: multiple datanodes on single node cluster
It is possible to run multiple datanodes.
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
