> If remote-app-log-dir is not created before starting Yarn processes, the 
> NodeManager creates it during the init of AppLogAggregator service. In a 
> custom system the primary group of the yarn user (which starts the NM/RM 
> daemons) is not hadoop, but set to a more restricted group (say yarn). If 
> NodeManager creates the folder it derives the group of the folder from the 
> primary group of the login user (which is yarn:yarn in this case), thus 
> setting the root log folder and all its subfolders to yarn group, ultimately 
> making it unaccessible to other processes - e.g. the JobHistoryServer's 
> AggregatedLogDeletionService.
> I suggest to make this group configurable. If this new configuration is not 
> set then we can still stick to the existing behaviour. 
> Creating the root app-log-dir each time during the setup of this system is a 
> bit error prone, and an end user can easily forget it. I think the best to 
> put this step is the LogAggregationService, which was responsible for 
> creating the folder already.
