**Edge Nodes**

So-called Edge nodes provide a common user access point for the MapR webserver and other client tools. Edge nodes may or may not be part of the cluster, as long as the edge node can reach cluster nodes. Nodes on the same network can run client services, MySQL for Metrics, and so on.

-----------------------------------------------------------------

However, I'm still not clear.

a) Why need 'provide a common user access point for the MapR webserver' ?

b) If I want to read/write to MapR-FS. It is just NFS mount point it .. or it is necessary to go thru Edge Nodes?


Thanks in advance.
