Is there any dependency when configuring Namenode HA, Ranger HA, Resource manager HA? What sequence should be followed?

[#1]

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-2.2.0.0/bk_Ambari_Users_Guide/content/ch_managing_s...

What sequence should be followed?

Are there any dependencies?
