Robert Kanter commented on MAPREDUCE-6415:
------------------------------------------
Yahoo! also has their own private implementation. So, it seems like there's a
need for something like this, and it would be great if everyone could use and
contribute to the same version of it.
YARN-2942 is being put on hold for the moment because of concerns about
HDFS-3689. We can still do it eventually.
As for MAPREDUCE-6283, I agree with Vinod's comment there that it seems to be a
duplicate of YARN-2942 for the logs part, and a duplicate of the ATSv2 work for
the jhist part.

> 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.
