Varun Saxena commented on MAPREDUCE-6415:
-----------------------------------------
[~rkanter], thats correct. We actually have a private implementation which
combines aggregated files into HAR files. It runs as a service in JHS and
combines aggregated logs periodically. From [~vinodkv]'s comment it seemed that
the community does not need it(because of YARN-2942) hence did not push it.

> Key: MAPREDUCE-6415
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-6415
> Project: Hadoop Map/Reduce
> Issue Type: New Feature
> Affects Versions: 2.8.0

> 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.
