Jesse Yates commented on HBASE-6949:
------------------------------------
To follow up on stack's comment, we don't actually have any directory heirarchy
for the logs right now - all logs regardless of source (e.g.
.logs/[servername]/[hlog]) just get moved to the .oldlogs directory. And since
we just added the HFileCleaner there aren't any existing implementations that
can be broken by automatically removing empty directories.

> Currently the CleanerChore asks cleaner delegates if both directories and
> files should be deleted. However, this leads to somewhat odd behavior in some
> delegates - you don't actually care if the directory hierarchy is preserved,
> the files; this means you always will delete directories and then implement
> the logic you actually want for preserving files. Instead we can handle this
> logic one layer higher in the CleanerChore and let the delegates just worry
> about preserving files.
