After the ip of the machine is modified, do not move the host name, modify the / etc/hosts file, and log in to the mysql database of cloudera manager by modifying the ip corresponding to each host name.

Mysql-uroot-pxxxxxx

Use cm

Modify the HOSTNAME field of the CM_VERSION table and the IP_ADDRESS startup cluster of the HOSTS table:

/ opt/cm-5.9.0/etc/init.d/cloudera-scm-server start

/ opt/cm-5.9.0/etc/init.d/cloudera-scm-agent start impala cluster can all be started without accident. If it is not started successfully, the browser accesses the ip:7180 of the first node of the machine, and starts the unstarted service in the browser. Or restart the machine, start the cloudera-scm-server,cloudera-scm-agent service and check whether the firewall and selinux are turned off
