## Configuring Topology Hierarchy
-Ozone determines Datanode network locations (e.g., racks) using Hadoop's rack
awareness, configured via `net.topology.node.switch.mapping.impl` in
`ozone-site.xml`. This key specifies a
`org.apache.hadoop.net.CachedDNSToSwitchMapping` implementation. [1]
+Ozone determines Datanode network locations (e.g., racks) using Hadoop's rack
awareness, configured via `net.topology.node.switch.mapping.impl` in
`ozone-site.xml`. The value of this key is the class name of an implementation
of `org.apache.hadoop.net.DNSToSwitchMapping`. [1]
:::note
Both Ozone Manager (OM) and Storage Container Manager (SCM) use network
topology information. It is critical to maintain a consistent topology
assignment across all OM and SCM instances in the cluster.
