Setting Up Topology and Replication
Procedure
- In the MapR Control System, open the MapR-FS group and click Nodes to display the Nodes view.
-
Set up each rack with its own path. For each rack, perform the following steps:
- Click the checkboxes next to the nodes in the rack.
- Click the Change Topology button to display the Change Node Topology dialog.
-
In the Change Node Topology dialog, type a path to represent the rack. For
example, if the cluster name is
cluster1
and the nodes are in rack 14, type/cluster1/rack14
.
- When creating volumes, choose a Replication Factor of 3 or more to provide sufficient data redundancy.
