>          Issue Type: Bug
>          Components: ambari-server
>    Affects Versions: 2.7.5
>            Reporter: Dmytro Vitiuk

> Now for each config update we calculate config changes for each host in the cluster.
There we are logging all config versions that are used for config changes calculation:
> {code}
> 2020-10-03 20:12:46,872  INFO [pool-28-thread-1] ConfigHelper:2051 - For configs update
on host 3 will be used following cluster desired configs {zoo.cfg={tag=TOPOLOGY_RESOLVED},
zookeeper-log4j={tag=TOPOLOGY_RESOLVED...
> {code}
> So in the case we have a lot of hosts in the cluster most server log capacity is spent
on config versions logging. We need to reduce logging level for some log calls in ConfigHelper.getHostActualConfigsExcludeCluster(...).
