Karthik Kambatla commented on MAPREDUCE-6415:
---------------------------------------------

LGTM too. Checked with Robert on the findbugs, looks like it was broken before the patch as
well.

> 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.
