Robert Kanter updated YARN-2942:
--------------------------------
Attachment: CompactedAggregatedLogsProposal_v2.pdf
I started implementing a rough prototype of the design and ran into a few
snags. I need to do more testing, but I believe I have a viable design now,
which I think is better anyway. I've uploaded a v2 design document with the
changes. I'm hoping to have a patch ready soon.
> Aggregated Log Files should be compacted

> Turning on log aggregation allows users to easily store container logs in
> HDFS and subsequently view them in the YARN web UIs from a central place.
> Currently, there is a separate log file for each Node Manager. This can be a
> problem for HDFS if you have a cluster with many nodes as you’ll slowly start
> accumulating many (possibly small) files per YARN application. The current
> “solution” for this problem is to configure YARN (actually the JHS) to
> automatically delete these files after some amount of time.
> We should improve this by compacting the per-node aggregated log files into
> one log file per application.
