> The dfs Datanode can only store data on a single filesystem volume. When a node runs
its disks JBOD this means running a Datanode per disk on the machine. While the scheme works
reasonably well on small clusters, on larger installations (several 100 nodes) it implies
a very large number of Datanodes with associated management overhead in the Namenode.
> The Datanod should be enhanced to be able to handle multiple volumes on a single machine.
