Changing hostname CDH5.7.X


Does anyone have a working procedure for this? We've tried numerous methods found on searching, but none have worked..  Using Hadoop, zookeeper, accumulo, kafka, SOLR..



are you trying to change the Cloudera manager server host name ? 

if so you can do it in 



change the Server_host  = (Hostname and ports of the Cloudera Manager Server and Agent and IP address of the Agent. ) 




Thanks for the reply! and yes, we've hit all the config files, but accumulo is holding on to the original name somehow, someway, and still have yet to resolve it.
