I don't know what is this "Database HA" feature but I can tell you what I
do.

I use Kafka channels and have multiple agents with the same configuration.
In front of the agents I have an http load balancer.
That way, any agent can accept requests and any agent can process them once
in the channel.

In addition, Cloudera Manager monitors are restarts agents if they die.

Regards,
Gonzalo
