----------------------------------------

[~rkanter], The patch looks good to me. You might want to clean up the TODOs and add some javaDocs though.
+1 pending that.

> 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.
