> Currently aggregated log cleaner service runs in MR Job History Server as "_AggregatedLogDeletionService_". Hence, any change in "yarn.log-aggregation.retain-seconds" in yarn-site.xml should enforce a restart of MR Job histotry server. However, we see only YARN service restarts to be prompted. So, there should be another restart icon that should pop up for MapReduce service for Job history server.

> Ref: YARN Log aggregation behavior is explained [here|https://hortonworks.com/blog/simplifying-user-logs-management-and-access-in-yarn/]
>  
> Steps to Reproduce
> ===============
>  # Make sure there are no stale configs (prompting restarts) in YARN or MR service page
>  # In YARN config page change "yarn.log-aggregation.retain-seconds" from default 30 days (in seconds) to any other value. 
>  # Save and observe the restart icon appear on just YARN service in Ambari UI.
