 ### Fixed
 
 - Fix Zookeeper hbase.rootdir when users point to discovery ConfigMap of ZookeeperCluster rather than ZNode. Print a warning in that case ([#394]).
+- Default `hbase.unsafe.regionserver.hostname.disable.master.reversedns` to
+  `true`, to ensure the names of RegionServers are resolved to their hostnames
+  instead of IP addresses ([#418]).
 
 ### Removed
