This may be a silly question....   But when setting up a node/cluster using the GUI, where do you specify the topology?   Using the default settings ends up creating an error "No Nodes in Volume Topology"   What's the root cause and how do you avoid this?   IMHO simple installs should result in simple systems without any inherent errors.

Having a problem where (it seems like) we are not able to see files that have been written to maprFS until some time (20+ seconds) after they have been written. What could be happening here? Is there some kind of underlying mechanism where mapr need to propagate new data across the cluster before it can be accessed (taking more than a few… (Show more)
