Need to configure RM HA

[#1]

Hi Team

I need to configure the RM HA on my QA environemnt.I am looking at below url to proceed

https://www.cloudera.com/documentation/enterprise/5-12-x/topics/cdh_hag_rm_ha_config.html#xd_583c10b...

but existing cluster environemt is enabled with TLS 1.0 sucurity for all the components, so in this case can i follow as above mentioned Url to enable RM HA ?

or do i need to do any extra steps , please help me

also please confirm work preserving recovery is enabled on RM by default not on NM correct ?

is it mandate on NM's to enable work preserving recovery ?

if i configure RM HA JHS will be removed from cluster ?

also any other components required to restart apart from YARN components(NM, RM) ?

zookeepers configured already and Namenode HA is enabled.

Please help me to get thsi done

Thanks
