Hi Currently holding 2 master nodes with 15 slave nodes cluster which will be expanded n the total would be 3 master nodes n 36 slave nodes. The HDP version is 2.6.5 I am looking to configure Namenode HA, Ranger HA, Resource manager HA in my cluster(non kerberised) and need some help in understanding which service to be implemented with HA first. Also, I would be implementing load balancer for Hive metastore, hive server2 and webhcat. I am following the below link for HA implementation: https://docs.hortonworks.com/HDPDocuments/Ambari-18.104.22.168/bk_Ambari_Users_Guide/content/ch_managing_service_high_availability.html What sequence should be followed? Are there any dependencies?
