Varun Saxena commented on YARN-2748:
------------------------------------
bq. To differentiate log files which may have same file names(due to
subfolders), I think we can write file path relative to container log directory
instead. Your views on this.
bq. Given Log Root Dir/sub-dir1/sub-dir2/.../xxxx.log, we can use the relative
path sub-dir1/sub-dir2/.../xxxx.log to uniquely identify a log.
[~zjshen], latest patch uses relative path to identify log in aggregated log
file. Kindly review.
> 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.
