+    The topology information of a host is determined by a topology mapping service defined by the

+    topology information from the file <code>org.apache.spark.storage.topologyFile</code>. Each line
+    of this file is of the format of <code>host1 = /rack1</code> and provides a mapping from a host
+    name to its rack information. <em>Note:</em> This configuration only takes effect when
+    <code>spark.storage.replication.policy</code> is set to a a policy that takes the topology
+    information into consideration, e.g.
