CDH 5.10.1, CentOS 7.3
I need to change move the cluster to new servers and change the IP address (all nodes including CM). Is there any known procedure to do so?
I thought of two possible methods:
1. Clone the servers, hunt for IP addresses in configuration file / SCM DB and update to new IP.
2. Reinstall CM on new server. Add and remove CDH nodes and let HDFS copy the data (our data volume is still small enough for this to be feasible)
Any better suggestion?
