> While we wait for YARN-2942 to become viable, it would still be great to 
> improve the aggregated logs problem.  We can write a tool that combines 
> aggregated log files into a single HAR file per application, which should 
> solve the too many files and too many blocks problems.  See the design 
> document for details.
> See YARN-2942 for more context.
