Vinod Kumar Vavilapalli commented on YARN-2748:
-----------------------------------------------
bq. One question is if we want to support a single-level sub folder or
recursive sub folders.
When I originally did log-aggregation before YARN got merged into Hadoop, I
intentially avoided sub-folders as it added unnecessary complexity and lacked
real life use-cases. What is the use-case for doing this now?
> Upload logs in the sub-folders under the local log dir when aggregating logs

> YARN-2734 has a temporal fix to skip sub folders to avoid exception. Ideally,
> if the app is creating a sub folder and putting its rolling logs there, we
> need to upload these logs as well.
