> If this [Map](https://github.com/apache/ozone/blob/4c65a07b124b21aa85aa3711035fd8616e13db38/hadoop-hdds/server-scm/src/main/java/org/apache/hadoop/hdds/scm/node/SCMNodeManager.java#L125) holds both IPs and Hostnames at all times, will this be an issue? In case we are in an ip changing environment and the ip doesn't work, hostname will still be available for the user. What do you think? Also, if you could provide a way for me to test it. This map is fine with IP changing environment since **we either use IP or hostname, not both of them simultaneously.** The prerequisite is the config ```dfs.datanode.use.datanode.hostname```. The maintainer should set the right config according to the environment. The simple test environment could be found in the ```kubernetes``` directory. E.g ozone/hadoop-ozone/dist/target/ozone-1.3.0-SNAPSHOT/kubernetes There is a README.md to teach how to set up an ozone k8s cluster. Kill/ Restart one DN pod could change the IP. -- This is an automated message from the Apache Git Service.
