> The UI needs to know in which host component installations have failed in
> order to add opportunity re-install them from pre-upgrade dialog. For now, we
> have this info only in "reason" string.
> Components installation info should have map between host and failed
> components.
> Now it is:

> The proposal is to add structured output to each of the upgrade pre-checks
> which could have automated UI actions associated with them. For example:
> {code}
> "failed_detail" : [
> {
> "host_name" : aantonenko252-1.c.pramod-thangali.internal,
> "service_name" : "HIVE",
> "component_name" : "HIVE_SERVER"
> },
> {
> "hostname_name" : aantonenko252-1.c.pramod-thangali.internal,
> "service_name" : "HIVE",
> "component_name" : "HIVE_CLIENT"
> },
> ...
> ],
> {code}
