Is there a feature for MapR-FS where a volume could be made from subset of node's disks (ie. when each node has 4 magnetic HDDs and 1 SSD, to be able to create a "hot" volume utilising only with those SSDs)?

There is not currently a way to assign topology to disks or storage pools; only to nodes. Label-based scheduling also works at the node level.
